LS376/515 Crate Engine

19301359 Chevrolet Motor


Big Power for Late-Model Vehicles

Using the LS3 engine as its foundation, the LS376/515 crate engine adds the ASA racing-derived 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.

The assembly includes LS3 cylinder heads with high-flow, rectangular-port intake passages, as well as an aluminum intake manifold. At the heart of the engine is that camshaft, which extends the performance range of the LS3 with more duration. 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 get the engine running. And if you’re installing it in an older vehicle, use our Muscle Car Oil Pan kit P/N 19212593.
