Description

MSD Pro-Billet crank distributors are built specifically for racing engines with almost no room for a distributor, due to tunnel rams or blowers. These units are equipped with a special low-profile crab-style distributor cap, allowing them to fit into extremely tight areas. The housing features two optional O-rings at the bottom that improves oil control by preventing oil pressure loss. Also, a small oil bleed hole (located in the base) sprays oil on the distributor and camshaft gears to prevent excessive wear.

Since these are racing distributors, there is an adjustable slip collar to make up for engines that have had the distance between the mounting surface and the gear modified. Crowning the Pro-Billet crank distributor is MSD's own crab cap. This incorporates spark plug-style terminals for a better connection and grip to the plug wires. Order the model recommended for your vehicle and engine application.
