Product Details

The COMP Cams High Energy 21-215-4 hydraulic flat tappet camshaft is designed specifically for Chrysler big block 383-440 cubic inch engines. This camshaft delivers improved performance over stock while maintaining excellent streetability and reliability with hydraulic flat tappet lifters.

Camshaft Specifications:

  • Advertised Duration: 268°/268° intake/exhaust
  • Duration @ .050": 218°/218° intake/exhaust
  • Valve Lift: .444"/.444" intake/exhaust (with 1.5:1 rocker ratio)
  • Lobe Separation Angle: 110°
  • Recommended RPM Range: 1,500-5,000 RPM
  • Recommended Valve Springs: COMP Cams #924

Performance Characteristics:

  • Smooth idle with slight lope for enhanced performance sound
  • Excellent torque curve for street and towing applications
  • Compatible with stock valve springs and components
  • Improved throttle response over stock camshaft
  • Works with stock to mildly modified cylinder heads

This High Energy series camshaft is ideal for street-driven vehicles, muscle car restorations, and daily drivers seeking a noticeable performance upgrade without sacrificing driveability. The hydraulic flat tappet design ensures quiet operation and eliminates the need for periodic valve lash adjustments.

Important Notes: New lifters should always be installed with a new camshaft. Use COMP Cams break-in lubricant during installation and follow proper break-in procedures. Compatible with both automatic and manual transmissions, though a higher stall torque converter (2,000-2,400 RPM) is recommended for optimal performance with automatic transmissions.

Had the part I needed at the best price.

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

Very easy purchase experience, new battery for my 2008 Prius fit perfectly! Hassle free, good price!

Very good customer service asked about a lot of different springs and parts for my Mazdaspeed 3.
