It depends on what you want. There is nothing wrong with running the Mopar electronic distributor. The ecu's can be sketchy though. If you want plug and play, the FBO ecu has modern electronics, uses a full 12 volts (no ballast resistor), has a rev limiter and their advance limiter plate and spring kit makes the factory distributor adjustable for a good timing curve. The cost is reasonable, and there is no cutting, splicing, wiring, routing, drilling holes, yada yada. Everything bolts in or plugs in to the factory locations. I use them a lot for street driven, or sleeper applications.
