Product Details

The COMP Cams Xtreme Energy 20-742-9 is a high-performance solid roller camshaft engineered specifically for Chrysler small block 273-360 cubic inch engines. This aggressive cam features 236 degrees of intake duration and 242 degrees of exhaust duration at 0.050" lift, delivering a strong mid-range to top-end power band ideal for street/strip applications.

Key Specifications:

  • Intake Duration: 236° @ 0.050"
  • Exhaust Duration: 242° @ 0.050"
  • Advertised Duration: 286° intake / 292° exhaust
  • Valve Lift: 0.570" intake / 0.580" exhaust (with 1.5:1 rocker ratio)
  • Lobe Separation Angle: 110°
  • Recommended RPM Range: 2,000-6,200 RPM
  • Solid roller design for maximum performance and durability

Performance Features:

  • Xtreme Energy lobe profile optimized for aggressive throttle response
  • Solid roller construction eliminates lifter flex for precise valve control
  • Designed for high-compression engines with aftermarket heads and intake manifolds
  • Produces a noticeable performance idle with excellent power delivery
  • Requires matching solid roller lifters, performance valve springs, and retainers (sold separately)

This camshaft is best suited for modified street machines, bracket racing, and performance builds where power above 2,000 RPM is the priority. Professional installation and proper valvetrain setup is required for solid roller camshaft applications.
