Best power from 3000 rpm - 6000 rpm. Includes camshafts, 4-gear set, gearcover gasket, bearings, retaining ring, o-ring, threat lock and instructions. Not for models with OEM compression releases.. The 330-0339 is the kind of component that earns its place in any build or repair by doing exactly what it is supposed to, every time. Sold as a complete kit.
