Chevrolet Performance 19301990 - LS3 Deluxe Power Upgrade Kit

(This Kit Includes Heads, Cam, & Components)

19301990
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. Contents include the LS7 camshaft, fully assembled LS3 CNC cylinder heads, and all components needed to complete the job.

NOTE: this kit is NOT LEGAL for street use and does NOT come with Executive Order (EO) D-126-45.
