Description

BluePrint Builder Series LS376/510HP Standard Edition EFI crate engine and T56 transmission combos take the guesswork out of matching up an engine and transmission for your ride. Featuring a fuel injected Chevy LS small block-compatible 376 (c.i.d.) engine that produces 510 horsepower, this standard edition builder series includes a polished pulley kit and T56 manual transmission. The aluminum BluePrint Engines cylinder heads help produce a nice 10.7:1 compression ratio, with assistance from the hydraulic roller camshaft, hypereutectic pistons, and nodular iron crankshaft. Altogether, this engine assembly produces 440 lbs.-ft. of torque. When you need or want a new powertrain for your ride, go with the authority in crate engines and their BluePrint Builder Series LS376/510HP Standard Edition EFI crate engine and T56 trans combos.
