Ford's engine history is long and storied from Flatheads to the 427 SOHC platforms that have been used in everything from hot rods to Bonneville to super speedways. To help blue oval enthusiasts keep their engines in tune, MSD now offers a Pro-Billet Distributor for the Y-Block engine that was used from '54-64! The Pro-Billet Y-Block Distributor, PN 83831, is built around a CNC-machined billet aluminum housing that is fit with a sealed ball bearing guide for stability and endurance. From timing accuracy, a maintenance-free magnetic pickup reliably triggers the MSD Ignition Control. For tuning, the Y-Block Distributor features MSD's easy-to-adjust mechanical advance. Different tension springs and a variety of stop bushings allow you to custom tailor a timing curve to match your application. There is also a vacuum advance that will help with economy during cruises and throttle transitions. The distributor is supplied with an MSD red, injection molded cap and rotor. It connects directly into the 2-pin connector of the MSD Ignition control such as a 6AL.
