This is our 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. For high RPM stability, a .500 In. 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 pick-up mounted in the housing. This high output magnetic pick-up is the most accurate way to trigger your ignition. Plus, with no moving parts to wear or adjust, the pick-up is maintenance free! Just above the pick-up 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.

The street Pro-Billet is a popular route for people looking for proven race performance for their street cars. A vacuum advance canister provides economy and the proven MSD mechanical advance gives you the opportunity to dial-in a timing curve to fit your needs. Inside, an oversized steel shaft is QPQ coated for low friction and rides in a sealed ball bearing at the top of the distributor with an extra-long sintered bushing at the bottom. This combination keeps the shaft steady creating accurate spark delivery at any RPM. The street Pro-Billet relies on a magnetic pick-up to trigger the MSD Ignition control which delivers the powerful sparks to the coil. This pick-up is extremely accurate and never needs adjusting.

Product Features:

• Designed for street/performance use w/mechanical or vacuum adv.
• Must Be Used w/An MSD Ignition Control
• Supplied w/An HEI Style Distributor Cap And Rotor
• Accepts Cap-A-Dapts
• O-ring seals can be installed for oil press. control (Mods only)

Marine environments place rigorous demands on every component of the ignition system. The combination of water spray, salt exposure, full throttle acceleration and harsh vibrations all take their toll. The MSD Pro-Billet distributor is the strongest and most accurate distributor you can put in your boat. The housing is CNC-machined from a billet of 6061-T6 aluminum creating a housing with no porosity. Each distributor uses MSD’s race-proven magnetic pickup to trigger the ignition control. Mounted just above the pickup is a mechanical advance assembly that is easy to adjust so you can dial-in an ignition curve to match your boat’s application (except PN 8366). For marine use, the distributor cap is bolted to the aluminum base. There are two flame arrestor holes with brass screens machined into the base of the distributor to prevent ignition of gas fumes that may build up in the engine compartment. A special Weathertight connector is supplied. Underwriter’s laboratory approved.

Product Features:

• For Use In Marine Applications w/Chevy V8 Automotive Engines
• Will not accept a vacuum advance canister
• Supplied w/Bolt Down HEI Style Distributor Cap And Rotor
