Our camshaft was joined by a set of APT’s precision chilled-iron lifters. A set of 1.5-ratio Harland Sharp aluminum roller rocker arms amplify that camshaft.

Cam timing is also of critical importance, so we employed an adjustable vernier-type double-roller cam gear. The previous timing set showed an uneven wear pattern, so we took extra care to perfectly align the cam and crank gears. To accomplish this, some material had to be machined off the back side of the gear. It’s the little things that help eliminate problems before they crop up.

Oil’s Well

Our race engine already had a well-designed pan and windage tray combination, but the unregulated oil system was producing unusually high pressures. Our solution: Integrate an adjustable oil pressure regulator into the system.
