The COMP Cams XR270HR Xtreme Energy camshaft offers a quicker valve opening for improved responsiveness and more area under the lift curve than older grinds, increasing torque and horsepower while retaining usable vacuum for accessories. It suits carbureted builds but shines with aftermarket intake manifolds, lower gears, headers and a free-flowing exhaust; expect a noticeable idle.
