The COMP Cams camshaft kit FS 283Th R7 Thumper ships as a full cam-and-valvetrain package with camshaft, lifters, valve springs, retainers, locks, valve stem seals, timing chain set, assembly lube for flat-tappet installs, decals and instructions. This high-performance street cam works with stock converters but performs best with a 2000+ stall converter and appropriate gearing, producing a choppy, thumping idle characteristic of its profile.
