The COMP Cams cam and lifter kit XR271HR pairs a matched camshaft and lifters and includes assembly lube, decals and instructions for a complete install. It suits ported heads but requires a serious valve-train upgrade and supporting components; the kit is best used with a 2200+ rpm stall converter and a programmer to tune fueling and timing.
