school me on dist

To recap (as best as I recall):
Truck was a Lean Burn 225, all of that has been removed - including the wiring for it.
Truck now has a points IGN system as an expedient way to get it running.
1930 would now like to convert it to Electronic Ignition with only Mopar parts and with a dist. that is tuned to work best in a truck.

The EI part seems simple to me, buy one of the kits or scavange those parts from the junkyard.

The tuned dist. is the part that will take some iteration. Since it is a truck that presumably will be used as a truck the usual spring kit(s) may not be the best plan. Their advance curve could easily be too aggressive for the application. I'm reminded of Smokey Yunick's words of wisdom about ignition timing "two degrees too little doesn't matter, two degrees too much is a disaster."
Good memory
