Sharing the CNC machining techniques with the rest of the MSD distributor line, the Oldsmobile housing is machined from high quality 6061-T6 aluminum. Adding to this?strength are two sealed ball bearings that guide the 0.500 In. shaft accurately through 10,000 RPM. Tig welded on top of the polished steel shaft is MSD's adjustable mechanical advance assembly. To accurately trigger the ignition, a high-output magnetic pick-up is bolted to the base. This trigger pick-up produces a precise trigger signal. An MSD red cap with brass terminals and race rotor are supplied.
