Product Details

The COMP Cams CL21-228-4 Xtreme Energy camshaft and lifter kit is designed for Chrysler 383-440 big block engines seeking increased mid-range power and aggressive performance characteristics. This hydraulic flat tappet cam delivers 241 degrees intake duration and 247 degrees exhaust duration, providing a noticeable performance upgrade with a lopey idle and strong power delivery from 2000-6000 RPM.

Key Features:

  • Hydraulic flat tappet camshaft with 241°/247° advertised duration
  • Hi-lift profile optimized for street/strip performance applications
  • Ideal for engines with aftermarket intake, headers, and 9.5:1+ compression
  • Xtreme Energy lobe design for maximum performance in hydraulic flat tappet applications
  • Includes matching hydraulic lifters for proper valvetrain operation
  • Complete kit includes camshaft, lifters, assembly lube, decals, and installation instructions

This cam kit works best with 2500-3000 RPM stall converters in automatic transmissions and 3.55 or higher rear gear ratios. The Xtreme Energy series is engineered to provide maximum power while maintaining hydraulic flat tappet reliability, making it an excellent choice for muscle car restorations and street performance builds.

quick delivery of the parts I need to fix my jeep

Great company to do business with! Ordered a Thule 916XTR bike rack for my car and their prices blew away everyone else on the 'net! Ordered on Sunday, they shipped on Monday and sent me a tracking number that night. Super fast shipping and great communication! I'll definitely be coming back to Autoplicity again!
