    The Leading Edge of Valve Train Technology

    Comp Cams Xtreme Energy series are perfect for any street or street/strip application where both throttle response and top-end horsepower is desired. These camshafts are designed to take advantage of the latest and greatest in valvetrain technology . Their aggressive lobe design produces better throttle response and top end horsepower than other cams with the same duration @ .050'' lift, while delivering increased engine vacuum. We do not recommend the use of stock valve springs with these camshafts due to the aggressive lobe designs.

    Features:
  • Quicker opening lobe profiles deliver increased responsiveness & more area under the lift curve
  • More vacuum allows an increase in duration for improved performance and assists power brakes
  • Excellent performance in street carbureted applications
  • Best performance with aftermarket intake manifolds, headers, lower gear ratios

    my motor has 250k+ miles , gonna replace cam and lifters have head machined, thinking about using sk20-221-3 cam set, but how do I know what valve springs to get??

    Asked by: Brandyn10
    These are the recommended springs for this cam kit - https://www.jegs.com/i/COMP-Cams/249/901-16/10002/-1

    How do you know what cam to get to run with the stock computer so you don't have to go get it re flashed or anything 

    Asked by: BM23
    This is the largest cam you can use without replacing the valve springs, this should work well in a fuel injected application - http://www.jegs.com/i/COMP-Cams/249/SK20-220-3/10002/-1
