BluePrint Builder Series LS376/530HP Standard Edition EFI Crate Engine and 4L65/70E Trans Combos
BluePrint Builder Series LS376/530HP 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 376 (c.i.d.) engine that produces 530 horsepower, this standard edition builder series includes a choice of black or polished pulley kits and 4L65/70E automatic 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 assembly produces 495 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 LS376/530HP Standard Edition EFI crate engine and 4L65/70E transmission combos.
