Most engines are designed with hydraulic or mechanical flat tappet camshafts, which meet the needs of regular production engines that seldom see 6000 RPM. Flat tappet cams are more than adequate for many competition engines. For ultra high performance applications where durability and high RPM capability are paramount, however, roller tappet camshafts are very popular. As the name implies, a cylindrical roller “rolls” over the cam lobe, instead of “sliding” as does a conventional flat tappet. This not only allows a roller tappet to follow a more radical cam lobe profile, but it reduces friction and lessens tappet scuffing of the cam lobes.
