Product Details

The COMP Cams CL11-604-5 is a high-performance camshaft and lifter kit designed for marine and drag racing applications in Chevrolet Big Block engines (396-454 cubic inches). This solid flat tappet camshaft features aggressive 256/266 degree duration specs that deliver strong mid-range to top-end power, making it ideal for racing engines that operate at higher RPM ranges.

Key Features:

  • Solid flat tappet design for maximum durability and high-RPM stability
  • 256/266 degree advertised duration provides aggressive performance profile
  • Engineered specifically for marine and drag racing applications
  • Compatible with Chevrolet Big Block 396, 402, 427, and 454 cubic inch engines
  • Complete kit includes camshaft, lifters, assembly lube, decals, and installation instructions
  • Mag marine/drag grind optimized for high-performance builds

This camshaft kit is designed for racing engines with upgraded valve springs, valve train components, and higher compression ratios. The solid flat tappet design requires periodic valve lash adjustment but provides superior performance consistency under extreme operating conditions. COMP Cams assembly lube is included to ensure proper break-in and long-term durability of the cam and lifter surfaces.

I ordered my K&N cold air intake order number 17133<br>From autoplicity for almost half price compared to other sites online. I will continue my purchases here n stop my searches elsewhere. And delivery time is fast!

Great Price! Fast Shipping!

Had to upgrade to a Snell 2010 helmet this year, bought the identical helmet for $200 less than I paid 8 years ago! Fast shipping, I will be checking Autoplicity first in the future!
