GM Performance Parts is pleased to announce the launch of our first crate engine in the LSX family.

GM has taken the heavy duty LSX block and combined it with the production LS3 components. This includes the High flow LS3 heads and an upgraded forged dished piston to keep the compression at 9.0 /1. This combination creates a high-revving LSX376 crate engine that runs on pump gas, A unique platform for any project.

The engine delivers exceptional air flow capability in a straight forward packaging even without any power-adder. The LSX376 is built without an intake manifold so you can top it with a carburetor or production-style injection system.

The LSX376 comes with only a dust cover instead of an oil pan so you can order what is correct to your application. Just one more way to keep the costs down and not include parts you can’t use.
