The COMP Cams XR268 Xtreme Energy camshaft provides quicker valve opening for improved responsiveness and more area under the lift curve than older grinds. It aims to boost torque and horsepower while maintaining usable vacuum for power brakes and accessories. Xtreme Energy grinds work well with aftermarket intake, lower gears, headers, and free-flowing exhaust, and suit carbureted applications with 9:1+ compression and a 2000+ stall.
