Product Details

The COMP Cams SK11-677-4 Xtreme Energy camshaft kit delivers aggressive performance for Chevrolet Big Block 396-454 engines. This complete SK-Kit (Small Kit) features a solid flat tappet camshaft with 236°/242° advertised duration, designed to deliver increased throttle response, strong mid-range torque, and top-end horsepower for street/strip applications.

Kit Includes:

  • Xtreme Energy solid flat tappet camshaft (236°/242° advertised duration)
  • Solid flat tappet lifters (16 pieces)
  • High-performance timing chain set
  • COMP Cams assembly lube
  • Installation instructions and decals

The Xtreme Energy camshaft line is engineered with advanced lobe profiles that maximize performance while maintaining excellent durability. This solid flat tappet design requires periodic valve lash adjustment but offers superior high-RPM stability and power potential compared to hydraulic designs. Ideal for big block Chevrolet engines in hot street rods, muscle cars, and weekend race vehicles where aggressive idle and strong acceleration are desired.

Application: Chevrolet Big Block V8 engines 396-454 cubic inches
