S-305-SB $2199
This engine is a great choice for the person who is looking for a good fuel efficient engine without sacrificing low end torque. GM designed this engine for mid sized cars and trucks to provide good power and be fuel conscious as well. This engines 3.766” bore and the 3.48” stroke provides good all around power and torque for most general applications. The compression ratio will be 8.8:1 with a 68cc cylinder head and uses a stage II 5.7” connecting rod. The street 305 engine is not a high RPM power house, however it does provide super reliable efficiency for most all street applications.
S-327-SB $2299
Everyone seemed to have forgotten about the super 327 engine, but we didn’t. This engine has quick RPM capabilities due to the larger 4” bore and the shorter 3.25” stroke. This engine is a great choice if one desires good mid range torque and power with great response. This engine is designed for a lighter vehicle that requires a higher RPM range and can have some fuel saving characteristics if the correct camshaft is used. This engine uses a stage II 5.7” connecting rod and the compression will be 8.5:1 using a 72cc cylinder head. The 327 engine is a good reliable engine for light cars and trucks using a lower gear and requiring a higher RPM range.
S-340-SB $2399
Not too many people know of this smaller cubic inch stroker engine but we know quite a lot about it. This little torque monster is the perfect combination of torque and power with a good potential of fuel economy. Designed for good low end torque due to the smaller 3.766” bore and the larger 3.75” stroke, this engine is a great choice for lower weight towing capabilities or a heavier weight car. This engine utilizes a stage II 5.565” connecting rod and has an 8.9:1 compression ratio using a 74cc cylinder head. This engine is not designed for higher RPM use, but is a good choice for one who needs the torque for towing or has a heavier vehicle with a higher gear. This engine can save some fuel as well due to the torque increases.
S-350-SB $2299
This is one of our most popular street engines. This engine features good all around torque and power capabilities and is a great choice for all cars and trucks for general driving or light towing requirements. The power and torque curves are larger due to the 4” bore and the 3.48” stroke and will work very well in most applications. This engine features an 8.8:1 compression using a 74cc cylinder head and uses a stage II 5.7” connecting rod. It is no secret that this is the most popular engine that GM has ever designed; however, we have taken this engine another step for better reliability and power capabilities.
S-3501pc-SB $2399
This is one our most popular late model one piece rear main seal street engine. This engine features good all around torque and power capabilities and is a great choice for all late model cars and trucks for general driving or light towing requirements. The power and torque curves are larger due to the 4” bore and the 3.48” stroke and will work very well in most applications. This engine features an 8.8:1 compression using a 74cc cylinder head and uses a stage II 5.7” connecting rod. It is no secret that this is the most popular engine that GM has ever designed; however, we have taken this engine another step for better reliability and power capabilities.
S-377-SB $2499
Our popular de-stroked 400 engine is a great choice for the person looking for better higher RPM power and quick throttle response in an engine. Great for a lighter car or truck with a lower gear that requires more mid-range power and torque. This engine utilizes a larger 4.125” bore and a shorter 3.48” stroke which makes this combination RPM quicker than most other similar cubic inch range engines. This street engine features an 8.7:1 compression ratio using a 74cc cylinder head and uses a stage II 5.7” connecting rod. Great for lighter cars and trucks requiring more efficient higher rpm service, this engine is also a popular choice for the performance street minded person.
S-383-SB $2599
This engine is the most popular engine that we build. Quite a few builders know about putting these combinations together but no one puts all the technology in the 383 engine that we do to promote maximum power and torque and great reliability. This is a great combination for the person who requires more power and torque than the 350 engine with the capability for general driving as well. This is a good choice for someone who is looking for an engine for towing or street performance due to the 4” bore and the larger 3.75” stroke. This engine features an 8.7:1 compression ratio using a 74cc cylinder head and uses a stage II 5.565” connecting rod. This is an excellent choice for higher mid-range torque and power for towing or street performance.
S-3831pc-SB $2699
This engine is the most popular late model one piece rear main seal combination that we build. Quite a few builders know about putting these combinations together but no one puts all the technology in the 383 engine that we do to promote maximum power and torque and great reliability. This is a great combination for the person who requires more power and torque than the 350 engine with the capability for general driving as well. This is a good choice for someone who is looking for an engine for towing or street performance due to the 4” bore and the larger 3.75” stroke.

This is an excellent late model engine choice for higher mid-range torque and power for towing or street performance.
S-400-SB $2799
Our larger cubic inch choice for the person who needs an engine that builds good all around power and torque. Great for heavier towing or for heavier street car performance, this engine will build the power and torque that one needs for more extreme uses. The large 4.125” bore and the 3.75” stroke provides good throttle response and wider power curves than the other small block Chevy engines. This engine has an 8.7:1 compression using a 74cc cylinder head and uses a stage II 5.565” connecting rod. This 400 engine is a great choice for the person who requires more power and torque in their small block engine.
Chevy Short Block Upgrades
** Our upgrades include the adjusted cost of all upgrade components, component assembly, related parts required for proper installation, all necessary extra machining procedures, and complete professional assembly.
UP-3750-INT-CRK $255
Internally Balanced Crankshaft
Our internally balanced 3.750” stroke crankshaft removes the external weight used for balancing to the inside and spreads evenly along the crankshaft. This decreases crank flex and snout deflection which provides a stronger and smoother running engine.
UP-BAL $295
Complete Balanced Assembly
Our competition balanced assembly provides a much smoother running engine, better throttle response and fuel economy. We equalize the weight of all rotating and reciprocating components, build the appropriate bob weights, and precision spin balance the crankshaft through the 8000RPM range. This insures less dynamic friction and more power and torque. Because any small imbalance multiplies with RPM, balancing can correct (In some cases) hundreds of pounds of effective imbalance which keeps the engine from fighting itself and relieves un-wanted stress on critical engine components.
UP-EXT-BAL $295
Needed for externally balanced engines.
These hand-picked quality components far exceed reliability requirements to provide a solid and reliable engine.
UP-INT-BAL $295
Needed for internally balanced engines.
These high quality components work to provide much less crankshaft harmonics than the factory counterparts and are much stronger to provide needed reliability.
UP-OP-KIT $145
Our blueprinted quality oil pumps provide proper oil pressure and volume required for engine lubrication. We also provide, properly install, and align the required oil pump pick up tube. For reliability, we use a new engineered steel shaft guide and heat treated oil pump drive.
