The COMP Cams FS 299Th R7 Thumper camshaft kit is a full cam conversion package including camshaft, lifters, valve springs, retainers, locks, stem seals, timing chain set, assembly lube, decals and instructions. Optimized for street/strip applications, it calls for about 9.5:1 compression and a 2800+ rpm stall converter with upgraded intake, gears and headers; very rough idle should be expected.
