LS376/515

SKU: 19370412

Affordable LS-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 533 horsepower at a stellar 6600 rpm and 477 lb-ft of torque at 5200 rpm. It’s the perfect high-performance option for a classic project car or racecar.

The assembly includes a Corvette 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.
