    The Leading Edge of Valve Train Technology

    Comp Cams Xtreme Energy series can be used in 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 improvements in valve train components and the newest developments in camshaft design. 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 train components 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

    I would like a torque converter recommendation. At what RPM would the most torque and horsepower be made with the stock heads and pistons? 

    Asked by: Alhoit
    This cam package has an RPM range of 1000rpm-5000rpm, this said you do not have to use a stall converter. If you wish for your application to accelerate a little quicker you could use a 1600rpm to 1800rpm stall converter.
