-This engine has a 2008-2009 Corvette style crank pulley.
Using the LS3 engine as its foundation, the LS376/515 crate engine adds GM 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 Chevrolet 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!
