MSD 83603 Distributor

Compatible with Small and Big Block Chevrolet® V8. This product is not created or sold by Chevrolet®. Black Ready-to-run distributors include a built-in ignition module-no MSD Ignition control required.;

This Black Pro-Billet Ready-to-Run distributor is the perfect upgrade for outdated points distributors or bulky HEIs.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 reluctors 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 reluctor an aftermarket EFI such as an Atomic EFI system.;
