Product Details

The COMP Cams K11-676-4 Xtreme Energy K-Kit is a complete camshaft package designed for Chevrolet Big Block 396-454 cubic inch engines. This solid flat tappet camshaft kit features a 230/236 duration profile that delivers aggressive performance with increased throttle response and horsepower gains throughout the RPM range, making it ideal for street/strip applications and performance builds.

Complete K-Kit Includes Everything You Need:

  • Xtreme Energy solid flat tappet camshaft with 230/236 duration
  • Matched solid lifters engineered for durability and performance
  • High-performance valve springs designed for increased lift and RPM capability
  • Precision valve spring retainers for reliable valve train operation
  • Valve locks (keepers) for secure valve spring retention
  • Valve stem seals to control oil consumption
  • Timing chain set for accurate cam timing
  • Assembly lube to protect components during break-in
  • Installation instructions and COMP Cams decals

This K-Kit eliminates the guesswork of component matching by providing a complete, engineered valve train package. The Xtreme Energy camshaft profile is designed to provide strong mid-range and top-end power while maintaining good street manners. As a solid flat tappet design, this camshaft requires periodic valve lash adjustment but delivers the aggressive sound and performance that enthusiasts demand.

Note: Solid flat tappet camshafts require proper break-in procedures and compatible valve train geometry. Professional installation and setup recommended for optimal performance and durability.
