The COMP Cams CCA camshaft kit XE274HR-12 is aimed at builds needing stronger midrange and top-end power, recommending a 2500+ rpm converter stall and 3.55–3.73 gears. The full kit includes camshaft, lifters, valve springs, retainers, valve locks, valve stem seals, timing chain set, assembly lube for flat tappet use, decals and instructions; it benefits from better heads, intake and fuel system upgrades.
