Description
BluePrint Builder Series LS427/625HP Standard Edition EFI crate engine and 4L65/70E 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 427 (c.i.d.) engine that produces 625 horsepower, this standard edition builder series includes a polished pulley kit and 4L65/70E automatic transmission. 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 565 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 LS427/625HP Standard Edition EFI crate engine and 4L65/70E transmission combos.
