BluePrint Builder Series LS427/800HP Standard Edition EFI supercharged engine and 4L80E transmission combos take the guesswork out of matching up an engine and transmission for your ride.

The aluminum BluePrint Engines cylinder heads help produce a nice 11.0:1 compression ratio, with assistance from the hydraulic roller camshaft, forged pistons, and forged crankshaft. Altogether, this assembly produces 780 lbs.-ft. of torque. When you need or want a new LS powertrain for your ride, go with the authority in crate engines and their BluePrint Builder Series LS427/800HP Standard Edition EFI supercharged engine and 4L80E transmission combos.
