Designed for street/performance use with a mechanical and vacuum advanceEasy-to-adjust mechanical advance with supplied springs and stop bushingsVacuum advance canister for improved economy (can be locked out)CNC machined billet aluminum housing and billet aluminum baseMaintenance-free magnetic pickup and precision reluctor create stable trigger signals throughout the RPM rangeThere is a big following of AMC enthusiasts that are cruising a 401 equipped javelin or trail blazing in a rock crawling jeep with an inline 6-cylinder. MSD offers two pro-billet distributors to deliver accurate trigger signals and are maintenance-free. Under the brass terminal cap of each distributor is MSD's race proven magnetic pick-up. This pick-up never requires adjustment and simply plugs right into an MSD ignition control. Just above it and under our strong race rotor is an adjustable mechanical advance assembly. The chro-moly weights of this assembly slide on nylon bushings producing smooth movement of the timing. You can easily adjust the curve to match your engine's requirements with the supplied springs and stop bushings. Each precision CNC-machined billet aluminum housing features a sealed ball-bearing and long sintered bushing for stability at any rpm and increased endurance. An oversized steel shaft receives a QPQ coating to reduce friction and prevent corrosion.
