About this item

Product details

Compatible with Oldsmobile® 260, 307, 330, 350, 400, 403, 425 and 455. This product is not created or sold by GM®. Must be used with an MSD 6, 7 or 8-series ignition.;

Sharing the CNC machining techniques with the rest of the MSD Distributor line, the Olds housing is machined from high quality 6061-T6 aluminum. Adding to thisÃ‚Â 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 reluctor the ignition, a high-output magnetic pick-up is bolted to the base. This reluctor pick-up produces a precise reluctor signal. An MSD red cap with brass terminals and Race Rotor are supplied.;
