I have this distrib that came with my roller motor. What electronics/ connectors/ magic boxes do i need to use this? Is P/N E4ZE-12131-AA
That is for a fuel injected car which I believe you are running a carb. You really need a standard duraspark distributor or old points type with a conversion.
You need a dizzy for an 85 Mustang GT with a manual transmission, and a Ford Duraspark II box or MSD 6. And a coil of course.
I just used my old points-type distributor with a Pertronix module and added a Ford Motorsport steel distributor gear to mate with the roller cam.
Oh, I hoped i could use it. I paid $10 for it so I could have the steel gear. I'm glad i didn't spend a bunch of time cleaning it up
knocked the gear off and use it, they cost more than $10. sometimes the roll pins line up on a different dist. but sometimes you will need to drill a new hole through it. Easiest cheapest route will be to use the points dist. and put a Pertronix kit in it. very easy to hook up, only 2 wires to run to the coil. Been running one in my truck for over 10 years and no problems.
