  • CNC machined billet aluminum housing is 3/8 inch smaller in diameter and 7/8 inch shorter than conventional Chevy V-8 distributors with the points type cap
  • Maintenance-free magnetic pickup and precision reluctor create stable trigger signals throughout the RPM range
  • Easy-to-adjust mechanical advance with supplied springs and stop bushings
  • Adjustable slip collar mounting flange for engines with modified deck heights
  • Polished steel shaft is QPQ coated and guided by a sealed ball bearing and extra long sintered bushing


This distributor was designed for racers and street rodder that have space limitations due to firewall interference, blowers or oversized intake manifolds such as tunnel rams. The distributor is 3/8 inch Narrower and almost 1 inch Shorter than a standard distributor. Proven performance features include a high output magnetic pick-up and precision machined reluctor for accurate ignition triggering. A fully adjustable mechanical advance allows you to tailor the advance curve to your specific application. Topping it all off is our own small diameter cap. This is molded out of durable Rynite material and comes with an optional wire retainer.

Honestly I never met or heard of anyone using this product that didn't have roller camshaft! With that stated. Why is this product sold without the proper bronze gear? Sad! Very sad!

Another excellent product from MSD.Same internals as the standard Pro-Billet distributor, but with the adjustable slip collar, allowed me to get an exact fit and engagement to my oil pump with my raised runner heads.
