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 533 horsepower at a stellar 6,600 RPM and 477 lb.-ft. of torque at 5,200 RPM. It’s the perfect high performance option for a classic project car or race car. The assembly includes a Chevy SS oil pan and LS3 cylinder heads, with high flow, rectangular-port intake passages, as well as our 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.
