Product Description

Affordable LS3-based high-performance for the street 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 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. Wind it out yourself and you’ll see what we mean!

You’ll need our LSX controller P/N 19171130 and Holley 770-cfm carburetor P/N 19170093 to finish off and fire up this bad boy!
