| Description_MKT | The Pro billet Early Hemi Ready-to-Run distributor earns its name with simple wiring. One wire to 12 V, one to coil negative and another to ground. That's it! A matching harness with a 3-pin Weathertight connector is supplied. These distributors are the answer to weak breaker points or rebuilt aftermarket models. Inside the billet housing there is a high-output ignition module. When the maintenance-free magnetic pick-up signals the module to fire, up to 7.5 amps is sent to the coil where a powerful spark is created. This improved spark output results in quick starts, snappy throttle response and terrific drivability. The distributors are equipped with a vacuum advance canister for cruising economy. Plus, there is a mechanical advance assembly that is mounted on top of the distributor shaft making it easy to adjust the advance to meet your needs. Another great feature of the ready-to-run distributors is their simple installation. All you need to do is connect three wires and you'll be cruising. |
