Product Details

The COMP Cams Xtreme Energy CL12-771-8 is a high-performance solid roller camshaft and lifter kit designed for Chevrolet small block engines. This aggressive cam features 242° intake and 248° exhaust duration at 0.050" lift, delivering substantial power gains in the 2,000-6,200 RPM range. The solid roller design eliminates hydraulic lifter fade and provides maximum valve control at high RPM.

Key Specifications:

  • Duration at 0.050": 242° intake / 248° exhaust
  • Advertised duration: 290° intake / 296° exhaust
  • Valve lift (with 1.5 ratio rockers): 0.525" intake / 0.540" exhaust
  • Lobe separation angle: 110°
  • Solid roller design for maximum performance and durability
  • Recommended compression ratio: 10.5:1 or higher

Complete Kit Includes:

  • Xtreme Energy solid roller camshaft
  • High-quality roller lifters
  • Assembly lube for proper break-in
  • Installation instructions
  • COMP Cams decals

This cam is ideal for aggressive street/strip applications and requires aftermarket valve springs, pushrods, and a performance valve train. Best suited for engines with aftermarket cylinder heads, headers, and a 3,000+ RPM stall converter in automatic transmission applications. Not recommended for engines with stock components or vehicles requiring smooth idle characteristics.
