LS3 Power Upgrade - Basic Kit

19300535 Chevrolet Power Upgrade Kit

40hp Increase, Heads and Camshaft only

LS3 Basic Power Upgrade Kit

P/N 19300535

Increase the power of the LS3 engine in your Camaro SS or Corvette by 40 horsepower with Chevrolet Performance’s high-performance heads-and-cam kit.*

Developed by Chevrolet Performance engineers as a direct replacement (tuning required) for the factory-installed heads and camshaft, 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 camshaft and fully assembled cylinder heads.

Basic Kit includes:

(2) 88958758     CNC LS3 Cyl Heads
(1) 12638426     LS7 Camshaft

 

Note: Heads and camshaft only. Head gaskets, exhaust gaskets, cylinder head bolts and other components must be purchased separately. To purchase a complete (Deluxe) kit with all the installation components included, use P/N 19301990.
