Distributor, MSD, Ready-To-Run, Buick Nailhead 322/364/401/425

This is the perfect upgrade for outdated points or HEI distributors. Designed for street driven cars, this system is built around a billet aluminum housing that is CNC-machined to exact tolerances. An oversized steel shaft is guided by a sealed ball bearing and an extra-long sintered bushing for high-rpm stability and endurance. Features an easy-to-adjust mechanical advance, along with a vacuum advance to dial in performance. Distributor has a built-in module that provides a much more powerful spark than any stock HEI.
