Using the LS3 engine as its foundation, the LS376/515 crate engine adds Chevrolet Performance's racing-derived ASA Hot Cam and a carbureted intake system to produce 533 horsepower at a high-revving 6,600 rpm and 477 lb.-ft. of torque at 5,200 rpm. It's a great engine for resto-mod classic and late-model muscle cars.
The assembly includes an SS oil pan and LS3 cylinder heads, with high-flow, rectangular-port intake passages, as well as their unique, spider-type carburetor intake manifold. At the heart of the engine is the ASA Hot cam, which extends the performance range of the LS3 with more duration. That means it holds open the valves longer, enabling greater airflow at higher rpm. Wind it out yourself and you'll see what we mean!
You'll need the LSX controller (p/n 809-19171130) and Holley 770-cfm carburetor (p/n 809-19170093) to get the engine running. And if you're installing it in an older vehicle, use Muscle Car Oil Pan kit (p/n 809-19212593). **REPLACES 19370412 WITH 19419868** **REPLACES 19419868 WITH 19432420**
