    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 work for a 2002 5.3 ls vortec motor

    Asked by: Ezzythemechanic
    No, you will need a kit for the LS series engine and it would use a roller lifter.

    Will this work in my stock 5.7 vortec In my 96 chevy 1500

    Asked by: Joshmartin426
    No, the stock Vortec heads are limited to a max gross valve lift of .475". You would need to go slightly smaller on the cam size.

    Do i need anything else thats not in this kit ?

    Asked by: Marcos_avila2
    Not knowing everything you have done to your motor we can not say for sure if other parts are needed. With a cam change you will want springs to match,you will need gaskets etc. Please give us a call 800-345-4545 where one of our Technical sales staff can assist you further.
