The Leading Edge of Valve Train TechnologyQuicker 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
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.
