Overview

The LS-compatible layout is a favorite for its rock-solid reliability and proven track record. This BluePrint 376 c.i. Pro Series engine is a street-ready powerhouse built for performance, delivering 525 horsepower and 460 ft-lbs of torque. It is ideal for restomods, street machines, and pro-touring builds. This engine features a high-strength BluePrint cast iron block with LSX-style features—thicker decks, reinforced webbing, and extended cylinder skirts for added durability. It is topped with LS3-style aluminum heads, a 10.7:1 compression ratio, hydraulic roller cam, hypereutectic pistons, a nodular iron crankshaft, and a BluePrint Engines Fabbed Aluminum Intake Manifold. This engine requires a non-weighted flex plate/flywheel and recommended fuel is 91 Octane. BluePrint Engines recommends a 2200+ RPM stall converter. The retro-fit oil pan will fit most 1955-1995 GM front engine, RWD, V8 cars. It is not for use in pollution-controlled vehicles or in dry sump applications and does not include an engine controller, wiring harness, or ECU.
