Product Details

The COMP Cams Xtreme Energy 12-773-8 is a high-performance solid roller camshaft designed specifically for Chevrolet small block V8 engines. This camshaft delivers aggressive performance characteristics with 254 degrees of intake duration and 260 degrees of exhaust duration, making it ideal for street/strip applications and high-performance street machines.

Key Features:

  • Solid roller design for maximum valve control and high-RPM stability
  • 254/260 duration profile optimized for excellent mid-range to high-RPM power
  • Designed for Chevrolet small block engines (262-400 cubic inches)
  • Xtreme Energy lobe profile provides aggressive performance with improved throttle response
  • Requires compatible roller lifters, valve springs, and pushrods (sold separately)
  • Recommended for engines with aftermarket cylinder heads and intake systems

This camshaft is engineered for enthusiasts seeking maximum performance from their small block Chevy engine. The solid roller design eliminates hydraulic fade and provides precise valve timing control throughout the RPM range. Best suited for race applications or aggressive street machines with supporting modifications including upgraded valve train components, higher compression ratios, and free-flowing exhaust systems.
