The COMP Cams camshaft kit is a compact cam package that includes camshaft, lifters, timing chain set, assembly lube, decals and instructions. The CBVI XR271HR-12 works well with ported heads but requires a serious valve-train upgrade, a 2200+ rpm stall converter and tuning adjustments; it’s aimed at builds where higher lift and duration are matched with supporting hardware.
