Xtreme Energy - The most recent cam series from Comp. These cams take advantage of the latest valvetrain technology to produce more power than other cams of the same lift and duration, with increased engine vacuum. 1965-1966 engines will require machining a groove into the rear cam journal. This may be done by any competent machine shop. Use the old camshaft as a guide, or contact the Comp Cams tech line (1-800-999-0853) for detailed information.
SK-Kit - The medium kit includes camshaft, lifters, timing chain set, assembly lube, decals and instructions. Cannot use stock springs. Requires thrust button and wear plate.
