GM Small Block Compatible 383 c.i. Engine - 432 Horsepower - Power Adder - Short Block Plus
Overview:
BluePrint BP38321SP GM Small Block Compatible performance short block engine has been dyno tested at our factory with a Holley Classic 750cfm Carburetor and H8002K Cylinder Heads and produced 436 horsepower and 443 minimum torque. Not every BP38321SP is Dyno tested. This performance shows the capabilities of this engine. Performance may vary depending upon what cylinder heads, fuel system and intake manifold you choose. This engine features a 4-inch bore which mathematically yields a 377ci with a 3.75-inch stroke. This customizable engine comes with timing cover, harmonic balances, oil pan, hydraulic roller cam, and a high-volume oil pump.Ā This power adder engine is engineered to handle any type of forced induction. Whether youāre adding nitrous, a supercharger, or turbos, this short block has the strength and reliability to take the boost.
