Distributor - Pro-Billet - Ready-To-Run - Magnetic Pickup - Vacuum Advance - HEI Style Terminal - Black - Big Block Ford / Cleveland / Modified - Each

Easy as 1,2,3… The MSD Black Ready-to-Run distributor line makes adding big ignition power and stealthy good looks to your Chevy, Ford or Chrysler a snap. With no ignition box needed, connect 3 wires and you're "Ready-To-Run".

The Pro-Billet Ready-to-Run distributor is the perfect upgrade for outdated points distributors or bulky HEIs.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 to 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 engines 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 a tach or an aftermarket EFI such as an Atomic EFI system.
