Our 540/555 Hydraulic Roller cam engine will produce 724 horse power at approx. 5900 rpm. The build sheet is at the lower part of this listing. This engine is an excellent choice for use in classic street rods, sport trucks, 4x4 trucks, and can be used as a daily driver. High mileage use is not a problem with this engine. This is engine may also be setup for use in larger work trucks, or motor homes. We can also set any of our engines up for marine use.
This engine will produce nearly triple the horse power of the original bbc 396, 427 and 454's and much greater torque. Pump gas friendly. For those wanting to put this engine in a classic car or sport truck, select cam choice # 1 or # 2 with the Hurricane intake. This engine will deliver very impressive power in the lower rpm range, and have a very high degree of drivability and long life.
Two year warranty, see details below.
This engine uses a brand new World Merlin IV block, (standard deck height) with all new internals.
This engine is designed to have a very high level of drivability, or street manners.
Here are a few good reasons why we think the Stage 7.0 engine is a better choice than any of the original equipment big block engines produced by GM.
1. The Stage 7.0 bbc engine will accelerate any heavy car much better than any of the underpowered original GM bbc engines.
2. The exhaust note from this big block engine is much deeper than that of the typical stock GM big block engines.
3. Installing this engine in heavy cars or trucks without killing acceleration, or having to deepen the final gear, and needing a huge stall converter is a real plus. This engine will accelerate a 7500 lb vehicle much better than any stock bbc engine.
4. Low maintenance and high drivability even in very heavy cars and trucks, while generating up to 724 hp at the same cost as building a 496 engine.
5. Longevity and reliability. You don't have to turn the engine to a critical rpm range to produce its max hp output. There's nothing unsafe about running an engine that's well built like this up to 5,800 rpm. The hydraulic roller cam is very reliable and will not require a bronze distributor gear, as it has a normal cast gear. Our aluminum heads use very high quality hardware. All of our valves are from PBM, and are considered to be very high quality valves.
6. Should you ever decide to sell your car, or truck with this engine, the resale value would be much greater.
We do a full test run using an engine test mule on every engine we build. The engine is run for two intervals of 20 minutes each, and every possible issue is addressed. When you receive the engine, it will be ready to install and run. We also include an engine stand as pictured, wheels included, and an engine lift plate.
As of 10/25/2016, we completed installation of our second brand new Super Flow 902S dyno. This dyno is dedicated for dyno testing and tuning on our bbc engine line only.

De-tuned engines with different cam and intake combos will move the torque into the low rpm range, and is very desirable if you're sporting around on the street, rather than all-out racing. The de-tuned version of this engine will also allow you to set the car up closer to stock and increase drivability to a very high degree. Throttle response is also noticeably better. We can help you with a cam and intake selection that best suits your needs.
The compression range will be approx. 10.5:1 depending on how we set it up based on your needs. The Wiseco forged pistons are highly resistant to the damaging effects of detonation.
The build sheet is as follows:

BBC WORLD PRODUCTS MERLIN IV BLOCK BORE 9.800" STD DECK HEIGHT

We now use all of the Merlin IV blocks in all of our BBC engine builds as of 7/17/2018. The Merlin block is light years ahead in overall construction as compared to any of the other blocks on the market. The main caps all have ARP hardware. Dimensional specs are spot on, and this has been an issue with other blocks we have used in the past. Many of the top engine builders, ourselves included, have found the new Merlin IV block to be superior to other blocks in numerous ways.
World Products has completely redesigned the famed Merlin Big Block Chevy casting, incorporating numerous improvements and new features to virtually every area of the block.
Designated the Merlin IV, this new block is offered in all popular sizes and deck heights and is sure to be a favorite among racers and professional engine builders.
The block is bored to size with our new Centroid touch probe machine. Few machine shops have a machine of this accuracy.

We also deck the blocks to an RA finish of approx. 15 or better. The decking procedure is also done by our Centroid CNC machine.

We often find many brand new blocks to have a sloping deck of up to 4 thous. When we're finished decking the block, it is within approx. .001 accuracy from end to end. Many machine shops fail to catch this as the machinery they use does not allow for such accuracy.

We then plate hone the block with our new Sunnen SV10 diamond hone machine. This is also a very advanced machine that hones the block with a finish unlike conventional machines.

The final step is to clean the block in our high pressure block washer.
Below are the specs of the rotating assembly portion of this engine.

WISECO FULLY FORGED PISTONS, RATED AT 800+ HP. WISECO PISTONS ARE 100% MANUFACTURED IN THE USA. THEY ARE ONE OF THE HIGHEST RATED PISTON BUILDERS IN THE COUNTRY.

The Wiseco forged pistons are rated very high in the street/strip performance industry. They are made using the 2618 aircraft alloy and have fully machined crowns. We prefer the 2618 alloy over the lower cost 4032 alloy. This alloy may fragment from the effects of detonation and if this happens, it can be very destructive to the engine. Those types of pistons are fine for stock or mild engine builds, but should never be used in carbureted engines built to high horse power levels. The forged 2618 alloy piston is much more resistant to the effects of detonation and heat.

Our Wiseco Forged pistons are custom designed with an increase in compression height. This has many advantages. Here are a few facts about compression height and deck height.
Our custom made pistons have a compression height that is .010 taller on bbc pistons, and .015 taller on sbc pistons, as compared to most all of the catalog pistons on the market. We find this to be a very valuable feature. Since our pistons sit at a taller than normal compression height, we only have to remove approx. .005-.010 off the deck surface of the block. Our goal is set the piston at zero deck (flush with the deck surface). This maintains the deck's thickness, making it much stronger than a block that has been cut down .025. The engine will also run a bit cooler with a thicker deck. It's well known that the deck dissipates much of the built up heat an engine generates. This also allows for future deck re-surfacing without compromising the integrity of the block. On our bbc engines, we actually leave the piston about .003 to .005 in the hole to allow for possible piston rock. Our sbc engines will have the pistons setting right at zero with the deck.

You may have noticed that our Wiseco custom made forged pistons are referred to as Racing Pistons on the package. This does not mean that the pistons are for racing only. This is a generic term, referring to their ability to be used in high performance applications as well as for street rod use. These pistons are perfectly designed for use on the street, as well as for medium to upper level drag racing.

We have built approximately 5000 engines using the Wiseco pistons. The engines have been for street rod and strip use. We have seen no problems, nor have there been any complaints. They are an excellent product in every respect.

These pistons are also suitable for use with nitrous or blower setups.

The picture below is a file photo of our Wiseco pistons.

MAHLE HIGH PERFORMANCE MOLY RINGS

Scat Crankshaft.
The picture below is a generic file photo of a Scat crankshaft.

Some of the benefits of the Scat crankshaft supplied with this assembly:
The material used in this crankshaft is manufactured from an exclusive Space Age material that was designed for high strength and fatigue resistance. The Scat cranks are the best value you will ever find. The Scat crankshafts are the best way to build a strong bottom end for, street rods, dirt and circle track racing, and drag strip racing. This crank is suitable for use up to approx. 600-650 hp.
Crank Polishing.
Pictured below is our ABS crank polishing machine in action. We polish the crank on every engine we build. This extends bearing life, keeps oil cooler, and with the reduced friction, a slight increase in horsepower is gained. Many machine shops fail to do this. The finish on most cranks are at the bare minimum of acceptance, and we know this can affect bearing life. We have measured the RA finish with our profilometer, and found it to be as high as 25 RA finish on many of the cranks. We bring that number down to below considerably.

We now use the Clevite bearings in our engines.

Our choice of rods are the SCAT COMPETITION SERIES rods with ARP-8740 cap screws.

The Scat Pro-Comp extreme duty I-beam rods should not be mistaken for ProComp rods. These rods are made exclusively by Scat, and have nothing to do with the ProComp company. The critical sizing and installation of the ARP cap screws is performed on a Sunnen machine in the USA by Scat Industries. These rods are excellent for those wanting the extra security offered by a rod with 7/16 ARP cap screws.
Take notice of the design of these rods. They are far superior to conventional style I-beam rods.
If you do a search on the Scat Pro-Comp rods, you will find a vast amount of info on many car forums. All of the info is 100% positive. These rods are run in engines that not only produce high horsepower levels, but also run at continuous RPM. Notice the general appearance in the pictures. These rods do look impressive. The style is reminiscent of a steel billet rod.
The fact that these rods are incredibly strong and well made, coupled with the fact they are light weight, made it an easy decision to use them in all of our high horsepower street/strip engines.
We have noticed some engine builders using low cost generic rods and crankshafts in their engines. These non-branded, (no-name) products are often poor quality in many ways. You will notice many of the low end engine builders fail to mention the actual brand of the rods or cranks used in their engines. Upon further investigation you will find such parts not to be a branded name product. They may label these parts with a name, but one that is totally unrecognizable in the industry. Our experience in years past with such rods and cranks has been disappointing to say the least. Besides the obvious issues such as incorrect sizing and machining that is difficult to correct, the questionable alloy these items may be produced from and the potentially incorrect heat treating methods used, could prove to be disastrous. Little can be done to verify this and nothing can be done to correct it. Failures of such critical parts will usually result in catastrophic damage to the engine. As you may have noticed, this is why we specify the brand name, and series of every part used in our engines.
Many of the inferior "no-name" rods on the market will also have "no-name" rod bolts in them. We have seen these bolts before, and they are very low quality. They don't have ARP's rolled thread design, and they don't torque down with the same characteristics as a genuine ARP bolt. It's not just a matter of having a different brand bolt in the rods; these bolts are low quality in many ways. They have been known to fail in engines to a much greater degree than a high quality rod bolt, and this failure usually causes catastrophic damage in the engine. Beware of rods that don't mention the rod bolt brand. As far as we're concerned, ARP bolts are the only brand we would ever use or accept in a set of rods.
Genuine ARP 8740 cap screws.

PRO RACE BRAND SFI HARMONIC DAMPER, 7.0 DIAMETER INCLUDED.

Pro-Race brand dampers are used on all of our engines.
We have noticed others using a low grade knockoff brand damper/balancer, and we have encountered them in the past. They are substandard in appearance, and are often out of spec. The timing marks were also poorly marked on some of the balancers we have come across. Another problem with low grade dampers is the elastomer bonding can lose its adherence to the inner and outer structure. This problem is referred to as a slipped damper. We have only encountered this once in 10 years with the Pro-Race brand dampers.

BILLET ALUMINUM TIMING POINTER. VERY FEW SELLERS FINISH OFF THEIR TURN KEY ENGINES AS WE DO.

We did not offer this billet timing pointer in the past. However, we noticed that there was a birds-eye view of the timing pointer from the driver side of the engine, so we decided to use these on all of our engines.

HEAVY DUTY SFI RATED FLEXPLATE MADE IN THE USA INCLUDED.

This SFI flexplate is made in the USA and will resist cracking and warpage to a very high degree. One good telltale in identifying a low quality flexplate is the lack of welding on each side where the plate mates to the ring gear. They usually have a pale grey color to them, as they are not coated, and will rust quickly. Ours are welded on both sides, and are much thicker than an OE plate, and are zinc dichromate coated.
We do offer this engine with a manual flywheel. In most cases we do have both sizes, 153 and 168 tooth, available.
Our CWT 5500 Balancer.
We do our own balancing with our new state of the art CWT 5500 Series balancers. The CWT 5500 is the ultimate for precision balancing. We now have three of these in our machine shop. We consider this machine to be highly advanced compared to the Hines balancer we once used. We balance every rotating assembly we sell within 2 grams or less at no extra charge. A balance sheet is included with your assembly.

Three CWT balance machines under one roof is a rare sight.

Our crew wrapping up for the day. Pardon the mess.

Bravo aluminum cylinder heads. 335cc runner size.

Assembled by us with premium PBM competition grade valves, Melling springs, Comp retainers, Comp Viton valve seals, Comp spring ID locators, Comp 10 degree locks.
Notice the multi angle valve seat cut. These heads are designed to very high standards.

Below are the actual flow numbers for the Bravo heads. These numbers are true and accurate. The testing methods we use are considered to be on the conservative side. Some choose to show flow charts for their heads that have been done in a way that shows numbers that are misleading in our opinion. We use the Bravo heads on most all of our bbc engines builds all the way up to the 572 engine. The horse power numbers they produce are exceptional as compared to any of the low to mid range priced heads on the market.

ARP HEAD BOLTS AND WASHERS AND ROCKER STUDS.

COMP ULTRA PRO-MAGNUM ROCKERS.

The new Ultra Pro Magnum™ Roller Rocker Arms not only live up to the lofty standards of the original Pro Magnums™, but they also take stud mount rocker performance, stability and value to a whole new level. The modern arched, web-like design delivers increased strength and rigidity while still reducing the moment of inertia and optimizing the dynamic balance.

Important notice.

If you've read our warning on engine builders using low grade no-name rods and cranks, a similar situation exists in the roller rocker market. We do not use or sell off-shore, (no-name) roller rockers, period. They have proven to be faulty in many ways. The center trunnions are not polished, nor is the center of the roller tip true to size or polished. Metal fragments are often left inside the trunnion housing and will cause destruction of the needle bearings. The aluminum alloys used are never aircraft aluminum alloys as are used in all USA made roller rockers. They often mention the alloy as being 6061, and that is a very soft form of aluminum. The 6061 alloy used on these will assure rocker-flex on any higher than stock spring pressures, and this will affect performance. The pins and keepers that hold the parts together are often of poor quality and improperly installed. The front roller will usually scoot along the valve tip, as it can't roll properly due to rough internal surfaces.

We have honestly seen valve tips that were scalloped out due to the front roller dragging across them. This will cause the valves to side-load against the valve guides in the heads and surely cause damage to them if run like this for very long.

We have scrutinized these products in the past and found all of the above problems, and I can tell you there are most likely many more. We would not use them in an engine under any circumstances. You will also see many of these rockers made from stainless on the market. They use a low grade stainless that actually has a near non-existent amount of nickel in them, but that's not the real problem with them, as stainless steel has no advantage over high grade heat treated steel when it comes to a roller rocker. The lack of hardness of the rocker body is the real problem. The problems with these stainless rockers are the same as mentioned above. These are the roller rockers you see on the market for around $119 and up to $169 for the so called stainless ones. They are pure junk, in our honest opinion. They could possibly be used on a budget back yard stock build up that has a very low spring pressure, with a cam that has very low lift, but then you would be better off with the stock stamped rockers on such a build.

We have heard of many engines using these rockers that came apart and spilled needle bearings into the engine, only to end up in the oil pump. It seems like some engine builders do not care how long the parts in your engine last, or they simply don't know this. I can tell you for sure that using such low grade, "no-name" roller rockers is asking for trouble.

We use Comp Ultra Pro Magnum rockers in all of our BBC engines. The difference in these compared to the low grade no-name rockers on the market is huge.
HOWARDS LIFTERS & HOWARDS CHROMOLY PUSHRODS.

We use Howards brand premium pushrods in all of our engines. They are lightweight in design, yet very strong. Made in the USA from 4130 chromoly steel. Regular hardened pushrods will most likely flex in the engine when running above normal RPM ranges, and risk bending under high RPM. These do not have the welded ball on the end. We only use the swedged one pc. design, which is a well proven design far superior to the style many others use in engines. 4130 chromoly steel is also much stronger, and will resist flexing. When a pushrod flexes in the engine, you lose lift. Don't be misled by the term "hardened," as this is nothing more than a stock style low cost push rod. They will flex in the engine or possibly bend permanently.
Our choice of lifters are the Howards brand tie bar lifters. These lifters have many unique features.
Pictured below is our Speedmaster single plane intake. We also offer the Edelbrock RPM Air Gap intake as an alternate choice.

304 STAINLESS ALLEN HEAD INTAKE BOLTS ARE USED ON ALL OUR ENGINES.

We are offering three cam choices listed below in this engine. Read the specs carefully.

Cam Choice # 1 By Comp Cams.
Part number: 01-461-8
575/575 lift.
254/260 duration
112 lobe sep.
Cam choice # 1 offers decent drivability and low end power. Valve train stability and longevity is very good with this cam. This cam is recommended for use in light to medium weight vehicles with tall gearing, and sport trucks. Max power will be achieved at approx. 5900 rpm. You may use the single plane intake with this cam and not affect the low end power to any noticeable amount.
We recommend a stall converter in the 2250-2500 rpm range. Final gearing when used in a car or sport truck could actually be in the 3.55 range or even taller, and overdrive use may be possible. Mileage with taller gearing is also a plus. This cam would be suitable in heavy vehicles weighing up to 4500 lbs. Drivability with this cam is decent. This cam may not develop enough vacuum to operate power brakes.

Official Dyno Results on Cam Choice 1 in our 555 engine with a single plane intake and our new 335cc rectangular port heads.

This is an excellent cam and head combination. Our new 335cc bbc heads have proven to be exceptional.

Official Dyno Results on Cam Choice # 1 in our 555 engine with a dual plane intake and flat top pistons. This engine had the low compression, (9.56:1) flat top pistons, and our former line of cyl. heads. Our new heads would have possibly exceeded these numbers especially with normal compression ratio. This setup would have been better suited with the Cam choice # 2 from what we're seeing. Low compression setups are for very heavy vehicles, and smaller cams are more in line with such setups. The smaller cam would have made better off idle power.

Cam Choice # 2 By Comp Cams.
Part number: 01-456-8
566/566 lift.
242/248 duration
112 lobe sep.
Cam choice # 2 offers a decent amount of bottom end torque compared to cam choice # 1. This cam selection is the best choice for cars that have very medium to tall gearing. This cam will allow the engine to operate well in the 1900-2000 rpm range. Very good acceleration with improved street manners. The peak horse power falls about 15-20 under cam choice # 1. This cam would also be excellent for medium to heavy vehicles. Max power is achieved at approx. 5700 or less. This cam has been very popular for those more concerned about drivability and outright longevity of the valve train and engine engine. The valve train wear with this cam would be very low. Off idle power is decent. We see no drawbacks to going with this cam. The power in the low rpm range is amazing. Vacuum should be enough for operating power brakes.

Official Dyno report with this cam choice, Bravo heads, a single plane intake, and an MSD distributor.

Cam Choice # 3 By Comp Cams.

Part number: 01-451-8
547/547 lift.
230/236duration
112 lobe sep.

Cam choice # 3 offers a huge amount of bottom end torque. This cam selection is the best choice for cars that have very tall gearing or overdrive transmissions. This cam will allow the engine to operate well in the 1800 rpm range. Very good acceleration with excellent street manners. The peak horse power falls an additional amount of about 15-20 under cam choice # 2. This cam would also be excellent for heavy vehicles, quad cab 4x4 pickups. Max power is achieved at approx. 5500 or less. This cam has been very popular for those more concerned about drivability and outright longevity of the valve train and engine engine. The valve train wear with this cam would be virtually non-existent. Off idle power is very good. We see no drawbacks to going with this cam. The power in the low rpm range is amazing. Vacuum should be enough for operating power brakes. Long range cruising and operating air conditioning is not an issue with this cam.
We have several different options in valve covers. Here are our most popular choices:

These are just a few of our popular valve covers you may choose from. We do have several more choices to select from in our other listings at no additional cost.

Billet Aluminum Breather set.

If you chose cam choice 1 or 2, then we highly recommend using an exhaust evac. system. The vacuum created by the engine is somewhat insufficient when using these larger cams, heads, carb and intake to operate a pcv system at its best. The exhaust evac system will pull the crankcase gases out of the engine at a very smooth and controlled rate. This allows the rings to seat in much faster and better, and can increase horse power to some degree by reducing crankcase pressure. Another benefit of the evac system is that you're not contaminating the fuel and air mixture with semi-burned byproducts from the engine oil and combustion process.
After the engine is completely broken in, the pcv setup may be sufficient. However, it may not be the best choice. The break-in time may also be slower with the pcv setup.
We also offer a vacuum pump system for the ultimate in crankcase pressure control.
If you do decide to use an exhaust evac system, we have a few more recommendations. The bullet style perforated mufflers, like those made by Magnaflow and many other companies, must be used. In our opinion, they sound the best and, most importantly, they allow the exhaust evac system to work properly. Magnaflow is a popular brand of the true straight through mufflers, and there are several other brands on the market such as Corsa, Borla, and Bullet. The sound level is controlled by the length you choose. The 12-16 inch length sounds the best to us. These mufflers have smooth perforated inner walls. They should not be confused with traditional glass packs with fluted walls, which are very restrictive and have a somewhat sloppy sound.
Traditional chambered mufflers, like Flowmaster, create a back pressure pulse that will interfere with the operation of an exhaust evac. system. Chambered mufflers have the reputation of helping bottom end throttle response, but you will have a decent amount of bottom end power with this engine, especially if you have chosen cam choice 2, 3 or 4. In our experience, the straight through perforated mufflers sound and perform better in every respect, and allow the proper use of an exhaust evac. system. More info. on this subject below.

Timing components: SA Gear 8999T billet double roller timing set.
Polished Aluminum Timing Cover.

We use the top of the line SA Gear timing set with a torrington bearing and rolon chain. The difference in quality is dramatic compared to the common low-cost timing set. The upper sprocket is made from billet steel and the lower is induction hardened with nine keyways. These sets are hand matched for selective sizing.
The cost on this high end timing set is approx $97.50, more than double the cost of the low level budget timing set used by many other engine builders. Should you ever want to confirm that this is what is actually in your engine, you can remove the timing cover, and you will see that this timing set is very different in appearance to the run of the mill low cost sets often used by others.
This timing set is offered in three different chain tension setups, allowing us to set it up perfectly every time. One more benefit is that timing accuracy is very precise and will remain that way. This timing set will likely last for the life of the engine. This is what you will find in most solid roller engines, as they have very high spring rates, and create an enormous load on the chain and gears, compared to non solid roller setups. It may seem like a bit of overkill to use such a high end timing set, but the versatility and extreme quality outweigh the cost, in our opinion.

Champ premium oil pan.
The oil pans we use on all of our engines are made in the USA by Champ. The Champ oil pan has a full windage tray, crank scraper, and trap door. Threaded dipstick is included. Extreme duty pickup designed not to fail. The oil pan is made from a thicker than normal gauge material, and has embossed ribs in the body.

The 7.5 qt Champ oil pan has kickouts that swell outward approx. 3 inches on each side. If you think you will encounter clearance issues with the kickouts, we recommend opting for the stock appearing 6 qt. oil pan. The 6 qt. pan will still be a Champ pan and will have the windage tray and crank scraper. We strongly recommend reducing the amount of oil used in these oil pans by approx. 1/4th to 1/2 a quart. Doing this may greatly reduce the chance of oil leaks, and reduce oil temps. The larger counter weights used on stroker crankshafts are why we recommend reducing the oil capacity in these engines.
To be clear on what we're saying, we would like to see you add right at 7.0 to 7.25 quarts of oil grand total in your engine and oil filter when using the higher capacity oil pan. When using the stock appearing oil pan, we would like to see you add right at 5.5 to 5.75 quarts grand total in your engine and oil filter.
Our engines include a dipstick. It's very important that you re-calibrate the oil level marking on the dipstick. This is due to the fact that the dipstick, oil pan, and block are all made from various manufacturers and we often see great variances. Couple this with the fact that you may be running a reduced amount of oil, and the "full" mark on the dipstick will most likely not indicate correctly. Once you have put a predetermined amount of oil in your engine, and run it for a few minutes, let it sit for awhile on level ground, check the oil, and mark your dipstick with a flat file to re-establish the full mark.

The quality of these pans far exceed any of the lower priced oil pans used on many engines.
We do not use the knock off oil pan gaskets on the market. Felpro premium oil pan gaskets are used on all of our engines.
Pictured below is a file photo. The actual Felpro gasket used will be the correct model for this application.

Studded Mini Nut Set.

We use our premium studded mini nut set on all of our oil pans and valve covers. The nuts have a serrated face and built in washers. This is the ultimate set for securing the oil pan and valve covers to the engine and is far superior to the typical bolts used by most other engine builders. Our standard engine color is black. Custom paint work on engine blocks and oil pans is available as an optional upgrade. The pictures above and below are file photos to display the studded mini nuts. Other items seen in these pictures may not represent your actual engine.

Melling M-Select Oil Pump, and M-Select Drive rod with ARP stud.

The M-Select series oil pump by Melling has several important upgrades compared to the regular Melling M-55 Series. The gears are billet steel, and the body is stronger, coated with corrosion-resistant nitrite. This oil pump also includes the M-Select drive rod. Both components are far superior to the regular Melling oil pump and drive rods used by most other engine builders.

Pictured below are the front end accessories that are included with this engine. They will be installed on the engine.
This is our satin high volume long style water pump with aluminum impeller. This is a very high quality pump.

Our 120 amp chrome plated one or three wire alternator.

Chrome plated power steering pump.

We are confident that the price we have on our engine will never be matched by our competition!
We include an engine lift plate and heavy duty engine stand with casters with every engine we build.

We offer this engine with selected upgrades and options. Listed below are some of the most requested ones. Many not only improve performance, but further enhance the reliability and longevity of your engine, along with resale value.
SFI Rated Billet Steel flywheel upgrade/option for manual transmission. Upgrade to a SFI billet steel flywheel 168-tooth or 153-tooth for manual transmissions. We highly recommend the SFI billet steel flywheel for those running hard. These are fully cnc'd and far superior in many ways compared to the regular cast iron flywheel.
Cost for the SFI billet flywheel option is $169.00 We have this upgrade/option featured in our other listings. There will be a Chevy 153 tooth and a Chevy 168 tooth size available. Be sure you know the size you need. You can see this and other upgrade options in our ebay store under the "UPGRADES" category, or simply do a search with the key word, "Upgrade" in the search bar when shopping in our ebay store. Before you finalize your purchase of this engine you may add any of these upgrades to your shopping cart. Click here to add upgrades.

BBC Scat H-Beam Rod upgrade from Competition Rods: Recommended for those running hard. The Scat Competition rods that come with this assembly are sufficient for most street rod uses, but the Scat H-beam rods will most likely offer more security against rod breakage under hard use. The H-beam rods have a 750+ HP rating.

Cost of this upgrade is $90.00 We have this upgrade featured in our other listings. You can see this and other upgrade options in our ebay store under the "UPGRADES" category, or simply do a search with the key word, "Upgrade" in the search bar when shopping in our ebay store. Before you finalize your purchase of this engine, you may add any of these upgrades to your shopping cart. Click here to add upgrades.

ARP-2000 rod bolts: This is one upgrade that we find to be very valuable. The rod bolts are most likely to fail under hard use, moreso than the rod itself. When a rod bolt fails during high RPM, total engine destruction is usually the result. The ARP-2000 rod bolts are a very good upgrade, in our opinion. We actually have few, if any, problems with the regular ARP-8740 bolts, but those who run hard always upgrade to the ARP-2000 rod bolts. The ARP-2000 rod bolts also torque at a higher number, and this increased clamping force is also a factor in keeping the big end of the rod stable and true to size. The ARP-2000 bolts are installed in the rods and this upgrade is only available with the Competition rod upgrade.
Cost of this upgrade is $89.50 We have this upgrade featured in our other listings. You can see this and other upgrade options in our ebay store under the "UPGRADES" category, or simply do a search with the key word, "Upgrade" in the search bar when shopping in our ebay store. Before you finalize your purchase of this engine, you may add any of these upgrades to your shopping cart. Click here to add upgrades.

BBC Scat 4340 Forged Crank: The forged Scat crank has a rating of 800+ HP. This is the ultimate upgrade for those wanting to run hard. Nos, blowers, turbos, are not an issue with this crank. Even without such power adders, this Crank offers great protection under the most severe conditions. This upgrade also comes with the HP high Performance King bearings. Should you decide to run power adders in the future, this would be essential. The fatigue life of the 4340 crank over the cast nodular is also greatly extended. We do offer this upgrade as part of many of our assemblies in some of our other listings. They have the key words, "fully forged," in the title.

Cost of this forged crank upgrade is $380.00 We have this upgrade featured in our other listings. You can see this and other upgrade options in our ebay store under the "UPGRADES" category, or simply do a search with the key word, "Upgrade" in the search bar when shopping in our ebay store. Before you finalize your purchase of this assembly you may add any of these upgrades to your shopping cart. Click here to add upgrades.

Polished Speedmaster intake upgrade:The polished intake upgrade is very popular, and certainly adds a bright fresh look to your engine.
Cost for the polished intake upgrade is $61.00 We have this upgrade featured in our other listings. You can see this and other upgrade options in our ebay store under the "UPGRADES" category, or simply do a search with the key word, "Upgrade" in the search bar when shopping in our ebay store. Before you finalize your purchase of this engine, you may add any of these upgrades to your shopping cart. Click here to add upgrades.

Dyno Tuning: This is one of the most important upgrade/options we offer. There are many benefits to this service. The engine is first run at fast idle to bring the water and oil temp up to normal operating temperature. It is then run for approx. 20 minutes under a simulated load at around 3k rpm to promote initial ring seating. After this, the engine is shut down to allow us to check the readings on the spark plugs, and for any possible oil leaks. This cool down is considered part of the engine's first heat cycle. We then follow up with multiple low to medium rpm runs to further the break-in process of all the moving parts in the engine. During these multiple runs, we are paying close attention to the EGT, (exhaust gas temp) readings, vacuum pump readings, oil temp and pressure, coolant temp, and overall engine sound. At this point, we start the actual dyno tuning process and this focuses around the air to fuel ratio numbers and what timing numbers produce peak power. We usually have to change carb. jetting several times, adjust the idle circuits, and the air-bleeds occasionally have to be changed. We then establish the engine's full horse power and torque numbers at a given rpm limit.
Having your engine dyno tuned will allow it to run its absolute best, and is very important in protecting the engine from potential damage caused by the carburetor running excessively rich or lean. This also establishes the engine's hp output and max rpm. These numbers are very important to know. There is one more value we consider just as important to what we have mentioned above. An engine that has been dyno tuned has also been validated to be in perfect operating condition. This is something that running the engine on a test mule can't provide. Any problems the engine may have will show up during the dyno tuning process. We have on rare occasion seen a popular combination show hp numbers that were not where they should be. Some of these problems give no indication other than reduced hp numbers. We find and fix such problems. The problem may be something simple and easy to find and in some cases very difficult to pinpoint. We will not send the engine out until it's perfect. If you choose not to purchase the dyno tuning package, we will still do a test mule run, as many engine builders do, and it certainly is better than nothing but pales in comparison to a full dyno tuning. When engines are dyno tuned, the chances of you having a problem are near non-existent. Unforeseen problems may still, occur but they are rare. We have kept the cost on this extensive procedure low to not only make it affordable, but it gives us great peace of mind knowing the engine will be in perfect operating condition when it is received. The cost to do a repair once the engine is installed can be very expensive for both us the seller and the customer. When you see the final dyno run of your engine on youtube, consider the fact that approximately five man hours, around $25.00 worth of fuel, oil and filter and $105K worth of dyno equipment went into making that one minute final test run video.
Cost of the full dyno tune option is $350.00 We have this upgrade featured in our other listings. You can see this and other upgrade options in our ebay store under the "UPGRADES" category, or simply do a search with the key word, "Upgrade" in the search bar when shopping in our ebay store.

Pictured below is one of our actual Super Flow dyno's. This is a 2016 model and highly advanced compared to the much older models many shops have. We have two of these in use at our shop.

The Super Flow is the best dyno in the industry.

WARRANTY INFORMATION

This engine is warranted, with limitations and exclusions as set forth below, for two years from date of sale.

Should a major problem arise with this engine within the first year of use, the warranty covers all parts and labor and we will pay for shipping the engine both ways.
Keep the crate your engine came in to ensure a safe return to our workshop.
We do not cover the removal or re-installation of the engine at any time during the warranty period.
Our engines must be used with a rev limiter. Should warranty issues arise, proof of the rev limiter use will be required.
Should a problem occur in the first year of the warranty that we determine can be repaired by you or a qualified repair shop, upon our written approval, we will pay for the repair based on our in-house hourly rates for labor and our estimate of a reasonable amount of time to make the repair with the engine on a stand as you received it. To be specific, due to the difficulty of accessing certain engine parts in some vehicles, we are not responsible for the additional time and labor costs you may incur in removing and replacing such parts.
In the second year, the warranty will cover all parts minus any labor to remove and install needed parts. The cost of shipping the engine to us is not covered in the second year of warranty.
Tuning or maintenance are not covered under the warranty. Tuning includes jetting or adjusting the carb, ignition timing, or readjusting the rockers. Tuning would also include changing out plugs to optimize temp range for your needs. Setting ignition timing is also considered tuning. You must check the timing on this engine before it is driven.
If you are not satisfied with the cam or intake you have chosen, we will exchange any of these items for up to 60 days. You will pay for shipping and any required labor.
Damage due to overheating, detonation or extreme abuse will not be covered by the warranty. Detonation damage is evident upon removal of the cyl. heads.
Engines used in marine applications will have a limited warranty of ONE year from date of sale. The first six months will cover parts and labor, and the second half of the one year period will cover parts only. Marine engines must upgrade to a 4340 crank unless the engine already comes with this, and the ARP-2000 rod bolts.
All external items on the engine, such as the carburetor, distributor, alternator, water pump, and power steering pump, will be warranted for the time period specified by the manufacturer. Most of these items have a warranty of one year or less.
Our engines are custom built to your specifications (e.g., cam choice, intake, engine color, compression ratio, and upgrades).
You can enjoy your engine with occasional spirited driving, as it is well designed for it, but we will not cover damage caused by racing or improper tuning. A rev limiter and fuel to air ratio monitoring device must be used on this engine. The rev limiter should be set to cut off at its peak horsepower or less if you choose, and this should allow many years of service without a problem.
Your carb should be tuned to allow the correct fuel to air ratio. This ratio can vary depending on many factors such as altitude, vehicle weight, gearing, type of driving, etc. These values should be in the recommended safe zone.
Pre-Installation/Pre-Run Recommendations.

It is highly recommended that you re-torque the intake manifold. The gasket sealant tends to shrink after a period of time and this may cause the intake bolts to lose their proper torque values. The torque range is approx. 25-30 lbs.
The spark plug gaps should all be re-checked. For those running an HEI distributor, the plug gap should be approx. .040-.045 Those running an MSD 6AL unit should gap the plugs to approx. .035-.040 These values are very controversial and you may experiment as to what runs best in your engine. Widening the gap too much can put a strain on the ignition components. Be sure your plug wires are completely fastened onto the spark plugs.
If your engine came equipped with a front end accessory setup, we recommend that you check all of the bracket and pulley bolts. It would be rare to find any of them loose, and it should only take a few minutes to check. We would also like you check the belt alignment.
Check your flexplate or flywheel bolts.
Check fuel bowl levels in the sight glass on the carb once you have the engine running. Be sure your fuel pressure is set in the correct range. Adjust the choke on the carb. We would prefer you set the choke to a loose setting. Setting it tightly may allow it do its job better, but can cause engine damage over a period of time due to excess fuel entering the engine upon warm up. Be sure to use a high quality fuel filter.

You may not find a problem with any of the items mentioned above, but considering the small amount of time it takes to check them, we find it to be a valuable preventive measure.
As it's been said, "an ounce of prevention is worth a pound of cure."
Continue reading for more detailed information on timing and carburetion. You must follow the recommendations listed below.
Tuning, maintenance, and oil recommendations.

This engine must be maintained with oil specifically designed for high performance engines. The life of the engine can be greatly extended if you run a race grade engine oil such as our Schaeffer brand racing oil. We strongly recommend the Schaeffer Micron Moly 20w-50 grade in warm to hot weather or you may run the 10w-30 weight Schaeffer Supreme 7000 series semi synthetic oil in cooler weather. The part number for this oil is 709-06 for the six qt. case or 709-12 for the full case. After the engine is fully broken in, you may move over the Schaeffer full synthetic oil. The Schaeffer brand oil is very highly rated. It is the only brand of oil we use when dyno tuning. Racing oil must be changed more often than conventional oil. Every 2000 miles or less would be optimal.
We offer a full line of this oil in our other listings.
Oil pressure of 50-60 lbs in the upper rpm range on a fully warmed up engine is nothing to worry about. You may also notice that oil pressure drops at idle to approx 25-30 lbs when the engine is fully warmed up during very hot weather. This is somewhat common and no cause for alarm.
If your engine has a Merlin IV block, then it has priority main oiling. This block routes the oil in a very different pathway compared to a GM block. The mains and rod bearings as well as the crankshaft are well protected with an ample supply of oil even when the oil pressure numbers are lower than you think they should be.
There are many special additives in race grade oils that are not in conventional oil. These additives are very valuable for high performance engines. Never add anything to racing oil. This oil has exactly what is needed to protect a high performance engine. Some of these oils will state that they are low or possibly non-detergent, and that is a desirable trait of racing oil.
The anti-foaming agents in race grade oils are much better than what you would find in conventional motor oil. Race grade oils have higher than normal amounts of the zinc compounds in them, and there are many components in the engine that can make great use of these additives.
This engine does not include a fuel pump. This engine is best suited to operate with an electric fuel pump, with a pressure regulator set at 6-6.5 psi. A chrome block off plate will be installed on the engine. We believe that the electric fuel pump system is a superior fuel delivery system compared to a mechanical system. If you decide to run a high volume mechanical fuel pump on this engine, then you must use the special polymer fuel pump rod that we offer, and you must also use a fuel pressure regulator, and gauge, set to approx. 6.0-6.5 psi. Only use engine oils with high levels of zinc compounds in them when running a mechanical fuel pump. This will protect the eccentric fuel pump lobe on the camshaft. We strongly recommend the Schaeffer Racing oil. See our other listings for this oil.
As for oil filters, we recommend a high quality oil filter. Racing oil filters are excellent. See our other listings for the recommended oil filters.
You must use a rev-limiter on this engine. Should you have a warranty issue, proof will be required. A rev-limiter will allow you the freedom to drive without having to monitor the tach. Every car from the factory has this feature. Set the limiter to the peak hp rating of this engine or less for added protection.
We strongly recommend using a crankcase ventilation system to pull gases from the crankcase. The exhaust evac system we recommend is made by Moroso. The benefits are numerous as compared to the typical pcv system. Oil leaks are greatly reduced by using the exhaust evac system.
Engine break in: As soon as your engine is installed, check and reset the timing if needed.
Drive safely please but keep your engine under load more than normal and bring the rpm up and back down to seat the rings much better and faster. This allows the rings to expand in a perfect circle and with greater pressure against the cylinder walls to establish an even wear pattern. This is why race engines are dynoed: to put a good number of passes on the engine under heavy load, as this will partially seat the rings very quickly, making the engine somewhat ready for racing. Failing to do this not only delays the break-in, but can permanently stop the engine from establishing a good wear pattern on the cylinder walls.
If you have opted for our dyno-tuned version of this engine, then ring seating will be partially established. The dyno has a computer controlled break-in mode that we use before doing any dyno testing for power output. Should you opt for the dyno tuning package, it does not mean that your engine is ready for full synthetic racing oil. Your engine will continue to seat the rings in to an even higher degree after 300-500 miles of driving.
VERY IMPORTANT NOTICE.
This engine does not come with oil in it. The oil that was used during the test run or dyno tuning will be drained as this is required by the shipping companies. We also prefer draining the oil as this gives us a chance to examine it for metal particles. The filter is removed and is also closely examined for metal particles or debris. To prevent oil from dripping onto the shipping pallet, we re-install the oil filter.

You must replace the oil filter that is installed on the engine with a high quality oil filter, but opt for the medium length version, as this will help maintain oil pressure and volume much better than the short version. See our listings for the recommended oil filters.

You must prime your new oil filter. Priming is not needed when changing oil on a well broken-in warm engine that has been running moments before changing the oil. If your new engine has been sitting around for weeks, or possibly months, then you must prime the oil filter.
.
The 7.5 qt Champ oil pan has kickouts that swell outward approx. 3 inches on each side. If you think you will encounter clearance issues with the kickouts, we recommend opting for the stock appearing 6 qt. oil pan. The 6 qt. pan will still be a Champ pan and will have the windage tray and crank scraper. We strongly recommend reducing the amount of oil used in these oil pans by approx. 1/4th to 1/2 a quart. Doing this may greatly reduce the chance of oil leaks, and reduce oil temps. The larger counter weights used on stroker crankshafts are why we recommend reducing the oil capacity in these engines.
To be clear on what we're saying, we would like to see you add right at 7.0 to 7.25 quarts of oil grand total in your engine and oil filter when using the higher capacity oil pan. When using the stock appearing oil pan, we would like to see you add right at 5.5 to 5.75 quarts grand total in your engine and oil filter.
Our engines include a dipstick. It's very important that you re-calibrate the oil level marking on the dipstick. This is due to the fact that the dipstick, oil pan, and block are all made from various manufacturers and we often see great variances. Couple this with the fact that you may be running a reduced amount of oil, and the "full" mark on the dipstick will most likely not indicate correctly. Once you have put a predetermined amount of oil in your engine, and run it for a few minutes, let it sit for awhile on level ground, check the oil, and mark your dipstick with a flat file to re-establish the full mark.
More tuning recommendations. Very important.
You must be sure that your air to fuel ratio is correct. We strongly recommend purchasing a fuel to air ratio monitor. Proper carb jetting is also a must. If you purchased the dyno package from us then the fuel to air ratio on your carburetor will be tuned within the safe ranges.
If you are using your own carb. on this engine, then you must be sure the fuel to air ratio is correct. If your carb is running too lean, detonation is at your door.
If it is excessively rich, cylinder wash-down from excessive fuel will destroy your bore finish, pistons, and rings quickly, not to mention cause excessive fuel consumption.
A tad on the rich side is not a problem and can help resist detonation; a tad on the lean side will generate the most power and increase fuel mileage.
The optimal air to fuel ratio is approx. 13:1 Set total timing at 30-34 degrees. Total timing refers to the reading at 4500 rpm with the vac. advance disconnected. The closer to the lower number (30 degrees) the total timing is, the safer your engine will be. Do not worry about initial timing, as it will be determined by the total timing.
We do not recommend running the vacuum advance with this engine.
Be sure to have a high amperage battery and high quality starter. The battery must be 850 cca or more. Use heavy gauge battery cables. If you have a hard cranking issue, purchase an in-car timing controller or ignition kill switch. This will allow you to control your timing for optimal performance and ease of starting.

Do not run regular gas in this engine, no matter how much you have reduced the timing. It may not be enough! You may have run an old car in the past that pinged and clattered under load for many miles, and this didn't seem to hurt it. Most cars from the 60's and 70's had very low compression, especially when nearly worn out, and this is why the detonation did not destroy the engine. Excessive pinging, spark knock or valve clatter, as it's often referred to, may destroy this engine very quickly. Light pinging now and then is unlikely to do any damage, but it certainly will when there is an excessive amount of it under load.
Let any engine with compression numbers above 10:1 clatter and ping for very long, and you will lose the engine due to detonation, and in some cases this can happen very quickly.

Spark Plugs: We recommend the Autolite brand, part number Autolite 3923. Most of our engines include the correct spark plugs. We also offer a premium NGK plug that is highly suitable for this engine when running in very hot climate. Race grade plugs are fine as they have a few features that are desirable for certain types of driving. Keep the temp in the low to middle range. Use a plug that's too hot, and you are once again close to detonation/pre-ignition; use a plug that's too cold and they will foul constantly, run poorly when cruising at low speed, and be difficult to start.
Most of our engines come with spark plugs in them, depending on the package you purchase. You may also use NGK part # NGK 4544, a plug that is one step lower in heat range than the Autolite plug. The NGK plug is only to be run during very hot weather.
You would be amazed at how much better an engine will run with the correct spark plugs installed, but brand name has little do with this. It's more to do with heat range than any other factor. Factors such as outside temp, altitude, compression ratio, and the type of driving you do determine the temp range to run.
A slight loss of power is also an issue with plugs that are too cold, as well as possible difficulty in starting. However, you can have much more serious issues by running plugs with high temp ranges.
Keep the engine coolant temp as low as possible, but it is not a problem if it runs as high as 210 on very hot days, as long as it's consistent, and not climbing.
Never use any of the modern day type antifreeze formulas that are used in most newer cars. This will most likely destroy the gasket material used in these engines. We have a customer that used the orange colored antifreeze made for Toyota trucks as he happened to have this on hand. This led to a failure of the high quality Felpro intake gaskets. The print seal material was partially dissolved allowing great amounts of coolant into the combustion chamber. This led to a catastrophic engine failure. The correct type of antifreeze to use should be ethylene glycol based, usually green colored. There are some animal safe substitutes on the market that should be ok to use. A mixture of 50/50 or even slightly less antifreeze will cool the engine better than a rich mixture of antifreeze. Keep the engine temp down if possible, but don't worry if you can't get it below 210 on a hot summer day. The cooler you keep the engine, the lower the risk of detonation. Set engine idle at approx. 900-950, and never too far below this unless you are running the smaller engine cam choices. The reduced size cams would allow for a lower idle speed.
Never let the engine idle for excessively long periods during the break-in period.
Do not overfill with engine oil. Slightly less than normal is better than too much, in most cases. Using half a quart less oil can greatly reduce potential oil leaks. This is a common practice in many high performance engines.
When setting your carb choke, we recommend setting it on the mild/lean side. It is best for the choke to open up to its full straight up position as quickly as possible. Keep backing it off until cold starting becomes difficult. Quickfuel brand carbs are best to run. They are also suitable for use on engines running a mechanical or electric fuel pump.
If the choke is set up on the aggressive side, it will create an over-rich condition upon every cold start-up and warm-up. This over-rich condition is very damaging to an engine, and will waste fuel.
If you feel you can get by without using the choke, then by all means do without it! The modern day carbs actually do well with very little or no choke. With a few pumps of the throttle and a bit of feathering, the throttle will have you off and going smoothly, in most cases with very little or no choking at all.
Hydraulic roller setups are virtually maintenance-free and require little if any maintenance.

Our recommendations will change from time to time. We never stop trying to build a better engine, and we learn from our own experiences and from feedback from our customers. We know there's always room for improvement. We're always working on research and development, as does any successful business. We advise checking out the recommendation section of our engine ads on a regular basis.

Why have we given such detailed information on our warranty and maintenance suggestions? Some customers bought our engines and did not fully understand our warranty and the maintenance needs of the engines.

Not knowing is understandable, but failing to educate yourself on the do's and don'ts is asking for problems. We suggest joining a few good car forums, as they have a wealth of great information.

However, beware of some individuals on forums who think they know it all, and really know very little. Do your research using several sources, and be sure to read between the lines.
