Product Details

The COMP Cams SK11-771-8 Xtreme Energy solid roller camshaft SK-Kit delivers aggressive performance for Chevrolet Big Block 396-454 engines. This complete small kit provides everything needed for a professional camshaft installation, featuring a 242/248 duration solid roller cam designed to maximize horsepower and torque in high-performance street and competition applications.

Kit Includes:

  • Xtreme Energy 242/248 solid roller camshaft engineered for Big Block Chevrolet
  • Matching solid roller lifters designed for high-RPM durability
  • Timing chain set for precise valve timing
  • Assembly lube for proper break-in and component protection

The Xtreme Energy cam profile offers an ideal balance of streetability and race-proven performance.

excellent service, i had to wait a few days for the order to be processesed, but only because i ordered on Friday afternoon, but love the site!

excellent ship time and exceptional pricing deffinatly will buy from here again

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

Smooth transaction, very pleased

Great company. Fast shipping and excellent communication. AAA+++

They made a mistake with the shipping address, but, they took care of it very politely and professionally. Very nice. Thanks.
