Die hard Oldsmobile enthusiasts have been asking about a ready-to-run distributor and here it is. Ready-To-Run means just that, drop it in the engine, connect three wires and fire up your olds. Inside the billet aluminum housing there is a high-output inductive ignition module that lights the spark. This module now has a built-in rev limiter to protect your olds from overrev protection damage. A polished steel shaft spins in the center of this module and is guided by a sealed ball bearing for great stability. Another great benefit of the MSD ready-to-run distributor is the mechanical advance. The weights and assembly are fine-blanked from chromoly for absolute precision resulting in smooth timing changes. You can set up a timing curve to match your engines specifications easily with the supplied advance springs and bushings plus there is a vacuum advance for economy. The distributor is supplied with the MSD cap, race rotor, wire retainer and gear.
