LS3 Power Upgrade Kit – Deluxe

Increase the power of the LS3 engine in your Corvette or Camaro SS by 40 horsepower 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), the kit includes our CNC-ported LS3 cylinder heads, which flow more than 350 cfm (intake side), with 276cc intake runners and 2.165"/1.590" valves. The high-lift LS7 camshaft makes the most of the heads' generous airflow attributes, holding the big valves open so the engine can process more air. This kit fits other LS-family engines with at least 4.000" bores. Includes cylinder heads, camshaft and components needed to complete the job.
