The COMP Cams Xtreme Energy camshaft CRH XR286HR-10 is specified for 1966–1971 Chrysler 426 Hemi 8‑cylinder applications and offers a quicker valve opening for improved responsiveness and greater area under the lift curve. Designed to boost torque and horsepower while retaining driveability, this grind performs best with supporting modifications such as improved intake manifolds, headers and free-flowing exhaust. Note: may produce a rough idle and requires supportive components.
