The MSD Pro-Billet HEI distributors pick up where the originals left off. Drawing on years of high-performance ignition experience, MSD engineers created a unique ignition module and internal coil that are capable of running above 9,000 rpm. Stock and other aftermarket modules lose spark energy at about 4,500 rpm. These modules produce 50 percent more current than stock units, and deliver a much more precise timing signal as well as more dwell control. The coil delivers over 100 millijoules of energy across the plug gap. For strength and high rpm stability, the QPQ-treated oversized shaft is guided by a sealed ball bearing on top and long sintered bushing at the bottom. 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 an adjustable mechanical advance assembly. The distributors are supplied with extra springs and stop bushings, so you can tailor an ignition curve to match your driving needs. The advance assembly features chromoly 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 distributors come complete and ready to drop in with a high-quality rotor and cap with brass terminals for great spark transfer. Simply connect a 12 V source to the distributor and you're up and running. They're designed to replace GM HEI distributors that use a 4-pin ignition module.

Flame-Thrower Race HEI distributors from PerTronix produce 42 percent more energy in the coil, with 46 percent faster spark breakdown time. This allows 48 percent more peak current to reach the spark plug, compared to their Street/Strip HEI distributors. That's an enormous improvement over stock HEIs and most aftermarket HEI distributors. A specially designed vacuum lockout mechanism prevents timing adjustments that change rotor phasing, adversely affecting the burn time and efficient fuel combustion. The rotor plates are TIG-welded to the mechanical advance mechanism, preventing high-rpm distortion and improving mechanical reliability. Each distributor uses a new aluminum housing cast and is machined from a strong, but lightweight A384 alloy. They're supplied with a high-dielectric strength cap with solid brass terminals, a balanced rotor, and a low-resistance center coil brush. Also included are nylon rotor hold-down screws and a factory-installed, high performance mechanical curve kit with precision-machined weights and a center plate. A hardened, machined steel gear is standard, along with an electronic module and coil combination that excels in the 6,000 to 8,500 rpm range. These distributors are great for both Circle Track and drag race applications where factory-type HEI distributors are mandated.

MSD Pro-Billet Ready-to-Run distributors are the perfect upgrade for weak OE electronic distributors, outdated points distributors, and large HEIs or DuraSparks. All that's required is to install the distributor in the engine, and connect three wires and the coil! A maintenance-free magnetic pickup accurately triggers this ignition with increased output from the amplifier, easily outperforming stock ignitions. It will smooth out the engine's idle, improve starting, and perform at a much higher rpm. The housing is machined from billet 6061-T6 aluminum, using state-of-the-art CNC mills and lathes for a unit with no porosity or weak areas. 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 distributors feature MSD's adjustable mechanical advance, which allows you to custom-tailor an ignition curve to match your engine's needs. Most models are also available with a vacuum advance canister to help improve economy. Order the model recommended for your vehicle and engine application.

Having a huge blower mounted on top of your engine is cool, but it can lead to limited choices for a distributor. The same goes for tri-power carburetor setups and big air cleaner assemblies, so MSD decided to morph their crab cap crank trigger distributor with a standard Chevy model to come up with a flat-top model! These MSD Flat-Top Pro-Billet distributors sit low in the engine block, and are topped with MSD's special crab cap that positions the spark plug terminals horizontally to give you plenty of clearance. These distributors incorporate a mechanical advance assembly that you can easily tune with the supplied springs and stop bushings. For trigger accuracy, a maintenance-free magnetic pickup is used. This pickup plugs directly into an MSD ignition control. The Flat-Top Pro-Billet distributors are supplied with a Dupont Rynite-molded distributor cap and rotor, along with a heavy-duty gear for long life in your engine.

MSD recognized the need for a true marine performance distributor and built these Pro-Billet marine distributors to answer this need. Marine environments place rigorous demands on every component of the ignition system, especially the distributor. The combination of water spray, salt exposure, full throttle acceleration, and harsh vibrations all take their toll. The housing is CNC-machined from billet 6061-T6 aluminum, creating a housing with no porosity or weak areas. Internally, a Tuftride coated steel shaft is guided by a sealed ball bearing and an extra-long sintered bushing for high-speed stability and endurance. Each distributor uses MSD's race-proven magnetic pickup to trigger the ignition control. The pickup receives its signal through a precision-manufactured reluctor that is attached to the shaft. The mechanical advance assembly receives a QPQ plating for long lasting resistance to corrosion in marine environments. Their mechanical advance assembly is easily adjustable, so you can dial-in an ignition curve to match your boat's application. Three additional sets of advance springs and stop bushings are included with detailed instructions, making adjustments easy to perform and understand. The distributor cap is bolted and sealed to the aluminum base, and has two flame arrestor holes with brass screens machined into the base of the distributor. This design works to prevent ignition of gas fumes that may build up in the engine compartment. A special weathertight connector is supplied to provide a positive lock and water-resistant connection. This heavy-duty connector will withstand high temperatures and water, and plugs directly into the MSD 6M-2 or 7M-2 ignitions. The distributors come complete with a high-quality, bolt-down alkyd cap and MSD's racing rotor. These high-quality distributors have been tested by the Underwriter's Laboratory, and are certified to meet or exceed safety standards for marine ignition systems as set by the U.S. Coast Guard. They require the use of a separate ignition box.

MSD Pro-Billet distributors share the same CNC machining techniques as the rest of the MSD distributor line. They feature a housing that's machined from high-quality 6061-T6 aluminum for durability and show-quality looks. Their oversized shaft receives a QPQ coating for friction reduction and corrosion resistance, with the added strength of two sealed ball bearings that guide the shaft accurately at well over 10,000 rpm. An extra-long sintered bushing replaces the ball bearing at the bottom of Chevrolet models. TIG-welded on top of the polished steel shaft is MSD's accurate mechanical advance assembly. The weights are supported by nylon pads that allow the advance to operate smoothly throughout the rpm range. For all-out racing, the advance mechanism can also be easily locked out. To accurately trigger the ignition, a high-output magnetic pickup is bolted to the base. This pickup produces a precise trigger signal that will never vary more than one degree at any rpm. A durable gear is installed for performance applications, and an MSD red cap with brass terminals and race rotor is supplied. They're available in standard and small diameter models for applications with limited clearance, and require the use of a separate ignition box such as an MSD 6, 7, 8, or 10 Series ignition.
