LS376/515 V8 Crate Engine
469 lb.-ft. @ 5,000 rpm 515 hp @ 6,500 rpm

Affordable LS3-based high-performance for the road or track! Using the LS3 engine as its foundation, the LS376/515 crate engine adds Chevrolet Performance's racing-derived ASA Cam and a carbureted intake system to produce 515 horsepower at a stellar 6,500 rpm and 469 lb.-ft. of torque at 5,000 rpm. It’s the perfect high performance option for a classic project car or race car.

The assembly includes a Corvette oil pan and LS3 cylinder heads, with high-flow, rectangular-port intake passages, as well as a unique, spider-type carburetor intake manifold. At the heart of the engine is the ASA cam, which extends the performance range of the LS3 with more duration. That means it holds the valves open longer, enabling greater airflow at higher rpm.

You’ll need a carburetor to finish off and fire up this crate engine.
