Cadillac cruisers will be excited about this new Pro-Billet Distributor for the 368, 425, 472 and 500 cubic inch engines. The Distributor begins life as a billet of 6061-T6 aluminum before being CNC-machined to precise dimensions. The sturdy, flex-free housing is fitted with a sealed ball-bearing and long sintered bushing for high-rpm accuracy. MSD’s race proven magnetic pick-up supplies a trigger signal that is accurate to within one degree at any rpm. Mounted above this pick-up is an adjustable mechanical advance and is supplied with different springs and stop bushings for a number of curves. For street cruising economy, as if there’s any such thing in a Caddy, there is a vacuum advance canister.
