Product Details

The COMP Cams Xtreme Energy Solid Roller Camshaft for Big Block Chevy engines is a high-performance roller camshaft for street/strip and performance builds. It uses a solid (mechanical) roller lifter design and is meant for builders who want stronger power output across the RPM range than a comparable flat tappet cam offers.

Key Features:

  • Solid roller design for aggressive lift rates and valve control
  • Part of the COMP Cams Xtreme Energy line of performance camshafts
  • Lobe profiles developed to improve throttle response and midrange and top-end power
  • Roller lifter operation reduces friction compared with flat tappet designs
  • Built for Big Block Chevrolet engine applications
  • Multiple grind options in the product line to match different engine combinations and power goals

COMP Cams has a long history in camshaft design and manufacturing. Each cam in the Xtreme Energy line is built for durability and consistent performance. Choose the grind that suits your engine combination, then pair it with matching roller lifters, valve springs, pushrods and other valvetrain parts for best results.
