The COMP Cams cam and lifter kit XR270HR includes a camshaft and lifters with assembly lube, decals and instructions. It offers strong mid-range power but requires supporting upgrades—headers, 3.55–4.10 gears and a 2000 rpm stall converter—and will produce a more noticeable idle, so plan tuning and driveline changes accordingly.
