Product Details

The COMP Cams Xtreme Energy 11-770-8 solid roller camshaft delivers aggressive performance for Chevrolet Big Block 396-454 cubic inch engines. This high-performance camshaft features 236 degrees of intake duration and 242 degrees of exhaust duration at 0.050" lift, making it ideal for serious street/strip applications and racing engines.

Key Specifications:

  • Intake Duration: 236° @ 0.050"
  • Exhaust Duration: 242° @ 0.050"
  • Solid roller design for maximum valve train stability and high-RPM performance
  • Designed for Big Block Chevrolet 396, 402, 427, and 454 cubic inch engines
  • Requires compatible solid roller lifters, valve springs, and retainers (sold separately)
  • Ideal for engines with aftermarket heads, aggressive compression ratios, and high-flow induction systems

The Xtreme Energy series camshafts are engineered for maximum power output in performance-oriented applications. This solid roller design eliminates lobe wear concerns associated with flat tappet cams while enabling higher lift and more aggressive ramp rates. Professional installation and proper valve train setup is recommended to achieve optimal performance and reliability.
