The MSD Pro-Billet Ready-to-Run distributor is the perfect upgrade for outdated points distributors or bulky HEIs. Simply install the distributor in the engine, connect three wires, the coil and fire it up! A maintenance-free magnetic pick-up accurately triggers the module. The increased output of the amplifier easily outperforms stock ignitions and will smooth out the engine's idle, improve starting and provide a much higher rpm range. The Ready-to-Run features MSD's adjustable mechanical advance which allows you to custom tailor an ignition curve to match your engine's needs. There is also a vacuum advance canister to help improve economy. For positive street performance, the Ready-to-Run is the best choice. Includes a separate tach circuit that is ideal to trigger an aftermarket EFI such as an Atomic EFI system.

MSD

What do a couple of missile engineers have in common with Corvettes? Well, it was a team of engineers from the White Sands Missile Range who founded MSD in 1970. As they were creating a lean-burn fuel system, they stumbled upon a new type of ignition system which could spark multiple times. Combined with the then-new technology of Capacitive Discharge, MSD found a potent new ignition system for cars. Most efficient when coupled with lean fuels, racers quickly picked up the technology and the legend of MSD was born. No matter whether your Corvette lives on the street or the track, Zip’s collection of MSD Ignition products can help your Corvette perform better and run smoother.
