Product Details

The COMP Cams Xtreme Energy SK21-224-4 is a complete small block camshaft kit designed specifically for Chrysler 383-440 cubic inch V8 engines. This hydraulic flat tappet camshaft delivers a noticeable performance upgrade with its 230°/236° advertised duration and aggressive lift profile, making it ideal for street/strip applications where strong mid-range power and throttle response are priorities.

Complete SK-Kit Includes:

  • Xtreme Energy hydraulic flat tappet camshaft with 230°/236° advertised duration
  • Matched hydraulic lifter set engineered for this cam profile
  • High-performance timing chain set for precise valve timing
  • Assembly lube for proper break-in procedures
  • Installation instructions and COMP Cams decals

Key Specifications:

  • Intake Duration: 230° advertised / 278° duration at .050"
  • Exhaust Duration: 236° advertised / 282° duration at .050"
  • Valve lift: .477"/.480" with 1.5 rocker ratio
  • LSA (Lobe Separation Angle): 110°
  • Recommended RPM range: 1,800-5,800 RPM
  • Rough idle quality, requires 9.5:1+ compression

This Xtreme Energy camshaft is designed for modified street engines and weekend racers seeking significant power gains without sacrificing reliability. The kit provides everything needed for a professional camshaft installation except valvesprings, which should be upgraded to COMP Cams part #986-16 or equivalent for proper valve control. Recommended for use with headers, performance intake manifold, and higher stall converter (2,400-2,800 RPM) for optimal performance.
