BluePrint Engines PSLS37681CTFKB LS 376 Pro, Deluxe Dressed, Blk

The BluePrint ever popular GM LS-Compatible 376 c.i. performance crate engine is packing a punch with 510 horsepower and 440 ft-lbs of torque, this powerplant is built to dominate. At its core lies a BluePrint Engines high-strength cast iron LSX-style block, paired with LS3 aluminum heads and a 10.7:1 compression ratio for optimal combustion efficiency. The hydraulic roller cam and hypereutectic pistons ensure smooth, reliable performance, while the nodular iron crankshaft adds durability under high stress. Fuel delivery is seamless thanks to the injectors and fuel rail kit, feeding into the LS3 cast aluminum intake manifold. A drive-by-wire throttle body and Holley Terminator X Max system provide precise control and modern tuning capabilities. Completing the setup are essentials like the LS swap oil pan, water pump, and gas pedal—making this engine not just powerful, but fully prepped for a clean, efficient swap into your next build. Adding a black front pulley kit with at LS2 style water pump, power steering pump with a remote reservoir, 140-amp alternator, and an air conditioning compressor.
