What Ignition to use

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.

If you don't mind the extra work and expense, the MSD is a nice system, but it isn't guaranteed to never give you problems. With electronics, anything can fail....instantly.
I've looked at the FBO set up and was quite impressed with it plus its made in the USA! I defiantly would consider it a solid upgrade.
