Overview

The BluePrint Engines PSLS37681CTFK is a powerful GM LS-compatible 376 cubic inch Pro Series crate engine. It produces 510 horsepower and 440 ft-lbs of torque. Key features include a high-strength cast iron LSX-style block, LS3 aluminum cylinder heads, and a 10.7:1 compression ratio. It's equipped with a hydraulic roller camshaft, hypereutectic pistons, and a nodular iron crankshaft. Fueling is managed by a Holley Terminator X Max EFI System, including injectors, a fuel rail kit, and an LS3 cast aluminum intake manifold. The engine also comes with a drive-by-wire throttle body, LS swap oil pan, water pump, gas pedal, and a polished front pulley kit (LS2 style water pump, remote reservoir power steering pump, 140-amp alternator, and an air conditioning compressor). This engine requires 91+ octane fuel and a non-weighted flex plate/flywheel. BluePrint Engines recommends a 2200+ RPM stall converter. It is not intended for use in pollution-controlled vehicles or dry sump applications. The ECU is pre-calibrated by Blueprint Engines.
