With the introduction of our 20 Amp extreme HEI module, we needed an HEI cap and rotor that could withstand the high output. The answer was to mold our own HEI cap, rotor and coil cover. The cap and rotor will fit our HEI Pro-Billet distributor, PN 8365, plus will work on stock applications.

Product Features:

• Extreme output rotor

Product Features:

• Replacement Canister
• Vacuum Advance Mechanism
• For Replacement On PN[8460/8461]
• Size Replacement Canister For Distributor PN[8360/8361]

The distributor is just one piece of this type of ignition system which is typically driven by the engine’s camshaft. The distributor is the device that delivers the ignition spark to the spark plugs at a precise time, and spark timing is critical. Any wear or component out of place in this type of system will result in failure. Within the distributor and mounted to it are many individual pieces which allow the distributor and system to be maintained and repaired to keep it in top working order.

Product Features:

• All products are constructed to meet all design and operating characteristics as intended by the vehicle manufacturer.

This bracket allows you to easily remove the vacuum advance from MSD distributors that are CW rotation (except PN 8365 and PN 8362).

Product Features:

• Vacuum Advance Lockout
• Distributor Accessories
• For Use On PN[8360/8361/8572]
• Size Can Be Used w/Distributor PN[8360/8361/8572]

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)

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.
