Product Details

The COMP Cams Xtreme Energy 20-812-9 is a hydraulic roller camshaft designed specifically for Chrysler LA small-block engines (273-360 cubic inches). This camshaft delivers an aggressive performance profile with excellent midrange power and strong top-end performance, making it ideal for street/strip applications and performance street builds.

Camshaft Specifications:

  • Intake Duration: 230° at .050"
  • Exhaust Duration: 236° at .050"
  • Advertised Duration: 276° intake / 282° exhaust
  • Valve Lift (with 1.5 rocker): .510" intake / .520" exhaust
  • Lobe Separation Angle: 110°
  • Hydraulic roller design for reduced friction and improved durability
  • Requires hydraulic roller lifters (not included)

Key Features:

  • Xtreme Energy lobe profiles provide maximum performance in street-driven vehicles
  • Hydraulic roller design eliminates break-in procedures required with flat tappet cams
  • Aggressive idle quality with noticeable lope
  • Optimized for engines with aftermarket cylinder heads, headers, and intake manifolds
  • Recommended RPM range: 1,500-6,000 RPM
  • Requires adequate valve spring pressure and compatible valve train components

This camshaft is designed for performance enthusiasts looking to extract maximum power from their small-block Chrysler engine while maintaining street drivability.
