Details

Specifically designed for use with the Holley Ford Hi-Ram carburetor intake manifolds, the Ford distributors are built on the proven foundation of the MSD Pro-Billet distributor line. They rely on MSD's race proven magnetic pickup and precision reluctor to deliver accurate trigger signals to the MSD Ignition throughout RPM range. The reluctor assembly is turned by a hardened steel shaft which rides in a sealed ball bearing for high rpm stability and endurance. Mounted to the top of this shaft is a fully adjustable mechanical advance assembly, and while at the bottom, you have a steel gear for use with hydraulic roller camshafts.
