Pro-Billet Ready-to-Run
The Pro-Billet Ready-to-Run distributor is the perfect upgrade for outdated points distributors or bulky HEI's. All that is required is to install the distributor in the engine, connect three wires and the coil!
A maintenance-free magnetic pickup accurately triggers this ignition. The increased output of the amplifier easily outperforms stock ignitions and will smooth out the engine's idle, improve starting and provide a much higher rpm range.
For stability and endurance, an oversized steel shaft spins in a top mounted sealed ball bearing while an extra long sintered bushing guides the shaft at the base of the housing. This shaft also receives a QPQ coating for low friction wear and resistance against corrosion from humidity and ozone buildup.
The Ready-to-Run features MSD's adjustable mechanical advance which allows you to custom tailor an ignition curve to match your engine's needs. There is also a vacuum advance canister to help improve economy. For positive street performance, the Ready-to-Run is the best choice.

NOTE: Supplied with a cap, rotor and vacuum advance. If replacing a GM HEI, a Blaster SS coil and coil wire are required (this is available in a kit, PN 8474).

Street Pro-Billet V8
The Street Pro-Billet is a popular route for people looking for proven race performance for their street cars. A vacuum advance canister provides improved economy and the proven MSD mechanical advance mechanism gives you the opportunity to dial-in a timing curve to fit your needs. As always, an advance kit of springs and stop bushings is included.
Like every MSD Chevrolet Pro-Billet Distributor, the housing features an all billet aluminum design for accuracy to within .001". 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 pickup to trigger the MSD Ignition Control which delivers the powerful sparks to the coil. This pickup is extremely accurate and never needs adjusting.
The Street Pro-Billet is CARB approved for use in all the states and will deliver race quality performance to your street car.

NOTE: Must be used with an MSD 6, 7, 8 or 10 Series Ignition. Supplied with cap and rotor.

MSD Pro-Billet GM HEI Distributor
 Originally, the GM HEI Distributor was a good economical plan with everything in one housing and easy installation. However, when it came to performance, it fell far short. That is why MSD engineers designed a Pro-Billet HEI Distributor along with a powerful ignition module and coil.
Drawing on years of high performance ignition experience, MSD engineers created a unique digital ignition module and internal coil that are capable of running above 9,000 rpm. Stock and other "performance" modules lose spark energy at about 4,500 rpm. The MSD module produces 50% more current than stock units and delivers a much more precise timing signal as well as dwell control. This module also has a built-in rev limiter!
For strength and high rpm stability, the QPQ treated oversized shaft is guided by a sealed ball bearing and long sintered bushing. The QPQ coating provides a low friction coating on the shaft and also makes it highly resistant to corrosion.
Tig welded to the top of the shaft is MSD's adjustable mechanical advance assembly. The distributor is supplied with extra springs and stop bushings so you can tailor an ignition curve to match your driving needs. The advance assembly features chrome moly weights that slide on nylon pads for smooth, timing advancement through the entire rpm range. There is also a vacuum advance canister to improve economy while cruising.
All of these features are enclosed in a great looking, billet aluminum housing that is CNC machined for accuracy and incredible strength. The distributor comes complete and ready to drop in with a high quality rotor and cap with brass terminals for great spark transfer. Simply connect a 12 volt source to the distributor and you're up and running.

NOTE: The PN 8365 is designed to replace GM HEI Distributors that use a 4-Pin ignition module.
