MSD SBC BBC PRO Billet Aluminum Distributor Small & Big Block Chevy V8

Part # 85551

This is MSD's most popular performance distributor! The housing is machined from a billet of 6061-T6 aluminum on a state-of-the-art CNC machine producing exact tolerances. Modified blocks can also take advantage of the O-ring seals to help maintain proper pressure. For high rpm stability, a .500" steel shaft is supported by a sealed ball bearing and a long sintered bushing. This shaft also receives a QPQ coating for friction reduction and resistance to corrosion. A precision machined reluctor is attached to the shaft which triggers the magnetic pickup mounted in the housing. This high output magnetic pickup is the most accurate way to trigger your ignition. Plus, with no moving parts to wear or adjust, the pickup is maintenance-free! Just above the pickup is MSD's adjustable mechanical advance assembly. Different springs and stop bushings are supplied so you can tune an advance curve to match your application. NOTE: Must be used with an MSD 6, 7, 8 or 10 Series Ignition. Supplied with a Cap and Rotor.
