Product Details

The COMP Cams Xtreme Energy 11-772-8 solid roller camshaft is engineered for Chevrolet Big Block 396-454 engines seeking aggressive performance with maintained street manners. This camshaft features 248/254 duration specifications optimized for high-performance applications.

Xtreme Energy Profile Benefits:

  • Quicker valve opening rate delivers increased throttle responsiveness and enhanced area under the lift curve compared to conventional cam profiles
  • Engineered to boost torque and horsepower while maintaining adequate manifold vacuum for power brakes and vacuum-dependent accessories
  • Solid roller design provides maximum valve control and durability for high-RPM operation
  • Optimized for Big Block Chevrolet engines from 396 to 454 cubic inches

Recommended Components:

  • Aftermarket intake manifolds for optimal airflow
  • Headers and free-flowing exhaust systems to maximize power gains
  • Lower rear gear ratios to complement the camshaft's power band
  • Works with carbureted setups; excellent performance with performance fuel systems

This solid roller camshaft delivers the performance characteristics serious enthusiasts demand while retaining the driveability and creature comforts expected from a well-engineered street/strip combination. Ideal for muscle car builds, street rods, and performance trucks requiring significant power upgrades without compromising everyday usability.
