Product Details

The COMP Cams Xtreme Energy 11-413-8 hydraulic roller camshaft delivers enhanced performance for Chevrolet Big Block 396-454 engines with a 212/218 duration profile designed to maximize torque and horsepower without sacrificing street manners. Featuring a quicker valve opening rate than traditional camshaft grinds, this Xtreme Energy profile increases throttle responsiveness and provides more area under the lift curve for improved power delivery throughout the RPM range.

Key Features:

  • Hydraulic roller design for reduced friction and increased valve control
  • 212/218 duration profile optimized for street/strip applications
  • Quicker valve opening characteristics for enhanced responsiveness
  • Maintains adequate vacuum for power brakes and vacuum-dependent accessories
  • Compatible with Chevrolet Big Block 396-454 cubic inch engines
  • Excellent performance with carbureted or fuel-injected setups

This camshaft is engineered to strike the ideal balance between performance and driveability, making it suitable for daily drivers that see occasional performance use. For optimal results, COMP Cams recommends pairing this camshaft with aftermarket intake manifolds, headers, free-flowing exhaust systems, and lower gear ratios to fully exploit the Xtreme Energy profile's potential.
