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.

MSD Pro-Billet Street distributors are a popular choice for those who desire race-proven performance for their street machine. A vacuum advance canister provides improved economy, and the proven MSD mechanical advance mechanism allows you to dial in a timing curve to fit your needs. As always, an advance kit of springs and stop bushings is included. The housing features an all-billet 6061-T6 aluminum design for accuracy to within .001 in. An oversized steel shaft is QPQ-coated for low friction, and rides in sealed ball bearings at the top and bottom of the distributor. An extra-long sintered bushing replaces the ball bearing at the bottom for Chevrolet models. This combination keeps the shaft steady, creating accurate spark delivery at any rpm. They rely 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. Pro-Billet Street distributors require the use of a separate ignition box, such as an MSD 6, 7, 8, or 10 Series ignition. Order the model recommended for your vehicle and engine application.

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.

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 Digital E-Curve distributors will drop right into your engine and fire up with three simple connections! Not only are there no external controls or boxes to mount and connect, but you can set a timing curve with the twist of a rotary dial! That's right, no more springs or stop bushings to fumble with. A new digital module lets you select from 20 different "centrifugal" curves and five vacuum curves--that's 100 combinations! Simply remove the cap to access the rotary dials and select a curve to match your application. You can also set an rpm limit that will protect your engine from over-rev damage caused by a missed shift or driveline failure.

Moroso billet aluminum spur gear oil pumps feature special anti-cavitation slots, feeder grooves, and an enlarged bypass area that is machined into the housing to bleed oil back to the inlet side of the pump. They combine to offer a smooth and consistent flow of oil, which improves the pumps' overall performance, extends engine life, and places an even loading on the distributor shaft to eliminate spark scatter. Manufactured using a proprietary casting process offering superior durability and reliability, the pump body and cover assembly are made to exact design specifications, while the gear and inner rotor shaft assemblies are matched to maintain absolute minimum clearances and provide maximum volumetric efficiency.

To make the most power from your engine, you need to optimize the air ingested and captured by avoiding valves closing too soon or too late. COMP Cams 4-pattern hydraulic roller camshafts are the first series of cams designed to accommodate a difference in runner length and avoid valves closing at the wrong times. Any conventional center-layout single throttle body or carbureted V8 intake manifold features longer outboard runners and shorter inboard runners, meaning that each valve event should occur at a different moment. COMP Cams has designed a series of cams that optimizes valve events and features a large increase in both area under the curve and stability at high rpm. They feature four different lobe patterns with one intake and exhaust design for outboard runners and another intake and exhaust design for the inboard runners. While the four central cylinders are all the same grinds, the outboard exhaust openings are two degrees earlier, with outboard intake closings coming two degrees later. NASCAR has been utilizing this technology for years. COMP Cams is now applying this same knowledge in street vehicles to balance air/fuel ratio per cylinder. These cams are CNC-ground from steel billet cores. They feature cast iron distributor gears and utilize a series of lobes with over .600 in. valve lift and stability up to 7,500 rpm, all while providing more consistent cylinder to cylinder torque. They also feature tight lobe separation for both excellent power and a throaty sound. Designed for small block Chevy, big block Chevy, and small block Ford carbureted or fuel injected applications, the design is exclusive and unique to COMP Cams.
