Product Details

  • Performance Pkg
  • If you want a little more out of your LS3 engine, meet this dynamic duo of CNC-ported heads and high-lift camshaft. This kit pair can increase the power of the LS3 engine in your Corvette to 470-plus hp and 440 lb-ft of torque. Developed by Chevrolet Performance engineers as a direct replacement for the factory-installed heads and camshaft (tuning required), with 276 cc intake runners and 2.165-inch/1.590-inch valves.
    The camshaft makes the most of the heads' generous airflow attributes, with .591-inch/.591-inch lift and 211°/230° duration at .05 inch and a 121° lobe separation angle. This kit fits other LS-family engines with at least 4-inch bores. Contents include the camshaft and fully assembled cylinder heads. Head gaskets (P/N 12610046) and cylinder head bolts (P/N 17800568) must be purchased separately.
