LS3
High-Performance Heads-and-Cam Kit*
19300535
Increase the power of the LS3 engine in your C6 LS3 Corvette to 470+ hp and 440 lb.-ft. of torque with Chevrolet Performance's high-performance heads-and-cam kit. Developed by Chevrolet Performance engineers as a direct replacement for the factory-installed heads and camshaft (tuning required), with 276cc intake runners and 2.165"/1.2590" valves. The high-lift camshaft makes the most of the heads' generous airflow attributes, with .591"/.591" lift and 211°/230° duration @.05" and a 121° lobe separation angle. This kit fits other LS-family engines with at least 4" bores. Contents include the camshaft and fully assembled cylinder heads. Head gaskets and cylinder head bolts must be purchased separately.
