Its durable, all-forged rotating assembly supports up to 15 pounds of boost. Our ratings of 473 hp and 444 lb.-ft. are only an indication of what the engine is capable of. Additionally, the engine is topped off with high-flow, LSX-LS3 6-bolt rectangular-port heads to create an affordable foundation for supercharged and turbocharged combinations. We deliver the LSX376-B15 without an intake manifold and other accessories, allowing you to tailor the induction system and other features to suit the forced induction setup of your choice. Chevy’s horsepower and torque ratings are based on testing with the production-style, normally aspirated fuel injection system. The power you make with a supercharger or turbo will vary.   Note: Oil pan and oil pump pickup are not included. LSX valve covers do not have coil mount provisions, coils will need to be relocated Note: New engines require priming of oiling system prior to initial start up. Don't see the crate engine you want?
