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

K12-238-2 - Comp Cams 'Xtreme Energy' Hydraulic Flat Tappet Camshafts is rated 5.0 out of 5 by 1.

Rated 5 out of 5 by Carlizle from great all around It really gave my stock rebuild some nice attitude

Date published: 2014-11-02

can i use stock SBC pushrods with this setup? also comp cams website says must use their roller rocker arms? this setup will be going on a Vortec head and non roller block combo

Asked by: bluelineengines

The stock pushrods work on most applications. There's too many variables to guarantee it works because that's such an important part of the valvetrain it needs to be checked upon assembly.
