This Black MSD Ready-to-Run distributor for the Chevy Small and Big Block is the perfect upgrade for outdated points distributors or bulky HEIs. Simply install it in the engine, connect three wires and the coil, and fire it up — a maintenance-free magnetic pick-up accurately triggers the module for smoother idle, improved starting, and a much higher rpm range.
