Since many Chrysler enthusiasts use the B1 head or aftermarket valve covers, these Pro-Billet Chrysler Distributors have been designed with a small diameter housing. This allows the distributors to fit tight block and head combinations. For accurate timing, a high output magnetic pick-up is used that plugs directly into your MSD Ignition Control. There is an easy-to-adjust mechanical advance mounted on top of each distributor and is easily tuned with an assortment of supplied advance stop bushings and advance springs.
