19301990 - CNC LS3 Cylinder Head and Cam Deluxe Upgrade Kit

Chevrolet Performance has engineered a new cylinder head and camshaft package for LS3-powered Camaros and Corvettes that pumps up the engine output an additional 40 horsepower! That's a 9% gain over stock! We've done that with our CNC -ported LS3 cylinder head that flows more than 350cfm (intake side), with 276cc intake runners and 2.165"/6590" valves. The high-lift LS7 camshaft makes the most of the heads' generous airflow attributes, with .558"/.558" lift and 211 degree/230 degree duration at .050" and a 121 degree lobe separation angle. And more than just a bolt-on (tuning required) for Camaros and Corvettes, this high-power kit fits other LS-family engines with at least 4.000" bores.

Package includes CNC LS3 cylinder heads, LS7 camshaft and components needed to complete the job.
