With this system - the Duraspark III, unlike the earlier Duraspark II, the advance is entirely computer controlled, and it uses the crank sensor, so there's nothing to the distributor but the cap and rotor.

If I still had the '72 Ranchero with the 302, I could have just taken the distributor out and tried that. (But I always preferred the way GM did their distributors so you could adjust the points with a dwell meter connected and the engine running - as opposed to Fords where you had to use the feeler gauge)

I'm tempted to try converting to the earlier electronic ignition system (the Duraspark II with an ordinary vacuum advance distributor and no crank sensor) - Looking around online I see people have done it, but I doubt that's something I could sort out quickly.

...Or I could get a points distributor and a 2 barrel carb (which I believe will fit on the same intake as the tbi), and just be done with this whole mess.
