BBC CHEVY HYDRAULIC ROLLER CAM EXTREME TORQUE  540/555 CUBIC INCH ENGINE 720  HP   This engine comes fully dressed out on the front as pictured above. The carb, distributor, wires and starter are not included with this engine. We have those items available in our other listings.   Important note. The picture above is an engine with our former line of cylinder heads. All of our bbc engines sold as of 2/26/22 will have the AFR Enforcer heads on them. They will display the AFR engraved logo in the front of heads as seen in the picture below of an engine we were in the process of building.

Our engines can also be built for use in marine applications. Pictured below is one of our bbc engines in a customer's boat. 

We also offer our engines with a lower cost basic front accessory kit, with electric water pump option and with no turn-key options at all  (base engine) . See all our engine listings. We also offer our bbc engines setup with a blower as pictured below.  RUNS ON PUMP GAS.

FULLY ASSEMBLED FROM INTAKE TO OIL PAN

Our 540/555 Hydraulic Roller cam engine will produce approx. 720 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 Generation Dart 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 720 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 NEW GENERATION DART BLOCK BORE  9.800" STD DECK HEIGHT

We now use the New Generation Dart blocks in our BBC 555 engine builds. The New Generation Dart block is light years ahead in overall construction as compared to any of the other blocks on the market. 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 Dart block to be superior to the earlier generation Big M series Dart block in many ways. 

Dart Machinery has completely redesigned the Big M series Block. They have incorporated numerous improvements and new features to virtually every area of the block. 

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.

Listed below is a complete breakdown of all the parts that are included in 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 mild nitrous or blower setups that do not exceed a 25% increase in horsepower over the engines naturally aspirated rating.

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.
