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

    Would this cam produce a noticeable idle, which I prefer. And at some later date I will be installing an ATI PB600 Procharger @ 9 PSI boost though a 650 Holley Double Pumper set up. Any suggestions or recommendations welcome.

    Asked by: Steve McDaniel
    I would not suggest using this cam with boost, there would too much over lap on this cam. I would look at their boost line cam for the such as 249-12-404-4.
