Overview

Designed for racing blocks with maximum increased deck height such as Alan Root, Merlin and Rocket Blocks. MSD offers this Distributor with an adjustable slip collar with nearly 3” of adjustment so you can be sure the distributor is installed correctly. The distributor shares the same features of the standard Pro-Billet Chevrolet model including a ball bearing guide, long sintered lower bushing and an oil seal. To trigger the MSD Ignition a maintenance-free magnetic pick-up is secured in the billet base of the distributor. Just above this pick-up assembly is an adjustable mechanical advance assembly.
