Description

BluePrint Builder Series 400/500HP Standard Edition EFI crate engine and 700R4 transmission combos take the guesswork out of matching up an engine and transmission for your ride. Featuring a fuel injected Chevy small block-compatible 400 (c.i.d.) engine that produces 500 horsepower, this standard edition builder series includes a polished pulley kit and 700R4 automatic transmission. The aluminum BluePrint Engines cylinder heads help produce a nice 10.3:1 compression ratio, with assistance from the hydraulic roller camshaft, forged pistons, and forged crankshaft. Altogether, this assembly produces 510 lbs.-ft. of torque. When you need or want a new powertrain for your GM ride, go with the authority in crate engines and their BluePrint Builder Series 400/500HP Standard Edition EFI crate engine and 700R4 transmission combos.
