Product Details

The COMP Cams Xtreme Energy SK11-772-8 is a complete solid roller camshaft kit designed specifically for Chevrolet Big Block engines (396-454 cubic inches). This high-performance cam features 248/254 duration specifications and delivers aggressive throttle response with a distinctive performance sound characteristic of solid roller designs.

Complete SK-Kit Includes:

  • Xtreme Energy solid roller camshaft with 248/254 duration profile
  • Matched solid roller lifters engineered for this cam profile
  • Timing chain set for precise valve timing
  • Assembly lube for proper break-in
  • Installation instructions and COMP Cams decals

This solid roller camshaft kit is engineered for serious performance applications where maximum power and aggressive lobe profiles are desired. The Xtreme Energy series delivers improved throttle response and power gains throughout the RPM range compared to flat tappet designs. Solid roller lifters eliminate the hydraulic damping found in hydraulic lifters, providing more precise valve control and the ability to run more aggressive lobe profiles with faster ramp rates.

Important Note: Solid roller camshafts require stiffer valve springs, proper pushrod selection, and careful setup. Professional installation is recommended to ensure proper lifter preload, valve lash adjustment, and timing set installation.

Fast shipping, great product. Nothing more needs to be said.

great price and customer service

They had the parts I needed at the best price. I needed some questions answered to make sure I was ordering the right parts for a 4 year old car and they were very helpful when I called.

Best price on the internet for my parts. Shipped out the next morning.

Finding my parts on this website was incredibly easy. The prices were the lowest around and I was kept up to date about the estimated delivery date. Order #19058
