Product Details

The COMP Cams CL21-232-4 Xtreme Energy camshaft and lifter kit is engineered for high-performance Chrysler big-block 383-440 cubic inch engines seeking aggressive throttle response and maximum mid-range to top-end power. This complete kit features a solid flat tappet camshaft with 244°/252° advertised duration and .501"/.509" lift (with 1.5 ratio rockers), delivering a pronounced lumpy idle and strong performance throughout the RPM range.

Key Features:

  • Solid flat tappet design for high-performance and racing applications
  • 244° intake / 252° exhaust advertised duration
  • .501" intake / .509" exhaust valve lift (1.5 ratio rockers)
  • 112° lobe separation angle for optimal power delivery
  • Designed specifically for Chrysler 383-440 big-block engines
  • Includes matching solid flat tappet lifters
  • Complete kit with assembly lube, installation instructions, and COMP Cams decals

This camshaft is ideal for street/strip applications with modified engines featuring upgraded valve springs, headers, and higher compression ratios. The Xtreme Energy profile provides excellent performance gains over stock while maintaining durability. Recommended for engines with manual transmissions or high-stall converters and 3.73+ rear gear ratios. Professional installation and proper valve train setup required for solid lifter camshafts.

this is my new home... very cool site, beat summit and jegs by $20 to $30

Great customer service. Fast order processing. Hassle free transaction.

Very fast shipping, received it Monday when I ordered it on Thursday. Thanks!

I found my part easily (vent visors), checkout was simple, and I was notified the very next day that my item has been sent. The price (including shipping) was way lower than anywhere else online or in town.

Received order very quickly and just as expected. The Eibach springs are great!

Autoplicity is awsome!! lowest prices.. fast shipping great customer service.. this is hard to find in todays world!!

Great service and communication. Once it was shipped, I was able to track my item. Best price I could find on the internet!! Would definitely do business with anytime.

best price around and quick order placement

Fantastic ! Ordered a Weather Tech Cargo Liner for my 2012 Ford Explorer. Price was $60 less here than ALL other sites on web. I was skeptical that this was going to be a counterfeit -- as the price was too good to be true. I was extremely happy to receive the genuine product as I expected in less than a week -- and for $60 less than the competitors ! GREAT VALUE and great service ! I will definitely be back !!
