Description Scat high performance camshaft kits are dyno tested and race proven to provide the ultimate on performance gains. Our Scat camshaft kits contain 1970 & earlier style 3 bolt style cam & gear (you will need to order the correct oil pump if your engine is 1971 and later) along with a complete set of scat performance lifters, valve springs, retainers and keepers. The C15-20053 kit is a Street & Strip performance grind. This cam has a heavy idle and will provide strong power from 3500-6500 RPM. Works best with larger displacement engines ( 2000cc to 2200cc) with modified heads and larger exhaust.
