CRATE ENGINE 6.2L LS3 515HP

533 Horsepower, 477 ft. lbs. Torque

Part Number: GM19435102

With the proven LS3 engine as its foundation, the LS376/515 crate engine matches the racing-derived ASA Hot Cam and a carbureted induction system to produce 533 horsepower at a stellar 6,600 rpm and 477 lb.-ft. of torque at 5,200 rpm.

The assembly includes an 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 Hot 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.

You?ll need our LSX controller P/N 19355418 and Holley 770-cfm carburetor P/N 19420445 to complete the engine and get it running. And if you?re installing it in an older vehicle, use our Muscle Car Oil Pan Kit P/N 19212593.
