LSX376 Crate Engine

Boost on a budget! That’s what you get with the new LSX376. GM Performance Parts takes the economical LSX Bowtie standard-deck block, adds blower-friendly 9.0:1 forged pistons and combines them with the LS3’s high-flow heads to create an affordable foundation for supercharged and turbocharged combinations. We deliver the LSX376 without an intake manifold and other accessories to keep the price lower and enable the installer to tailor the induction system to suit the blower or turbo system. Swap in the LSX376 in a vehicle originally equipped with an LS engine to give it a stronger bottom end for forced induction, or swap it into a street rod or classic muscle car body for a modern update. Our baseline horsepower and torque ratings are based on testing with the production-style, normally aspirated injection system. There’s no telling how much power you can realize with a carefully tuned turbo or supercharger system! NOTE: Due to the number of application variations, the LSX376 crate engine does not include an oil pan. See the LS Engine Components section for production-style oil pan choices. Also, the LSX376 valve covers do not include provisions for mounting the ignition coil brackets. Aftermarket or custom relocation brackets must be sourced.
