Designed as bolt-in cams for 103” engine with stock 9.7:1 compression ratio up to 10.5:1, giving you a level of quality that holds up across the full service life of the component. More power across the rpm range best results from 2500 rpm - 5500 rpm. Includes camshafts, gearcover gasket, bearings, retaining ring, o-ring, threat lock and instructions. Works with stock, un-ported heads, but is great for S&S CNC ported heads.. The 330-0303 delivers exactly what riders need from a quality aftermarket component. Sold as a complete kit.
