This Ready-to-Run Pro-Billet Distributor replaces a worn-out breaker-points distributor with a built-in inductive module that produces up to 7.5 amps for a high-voltage spark, improving combustion for quick starts, a smooth idle, and better performance. Since the module is built in, no separate MSD Ignition Control is required, and installation is a simple three-wire connection using the supplied weathertight harness.
