95 5.0 in a 65 distributor question

Probably the best way to go for low buck is a Duraspark II setup. This is the electronic ignition that came on Fords in the early 80s. The '85 Mustang distributor is supposed to have a good performance advance curve, that's not a bad way to go. You can get a rebuilt '85 distributor at a local parts store.

You'll need a steel gear to run on the roller cam.

Here's a good place for information.

There are so many options: you could go with MSD or Pertronix or some other aftermarket electronic ignition with a billet distributor. You could even keep your factory distributor and just replace the gear. Or you could use the factory parts with a Pertronix unit replacing the points. If it were me, I would at a minimum get the Pertronix ignition and get rid of the points. Oh, and I've heard that the large cap adapter is a good way to go.

Any points type or electronic for the early car will work, as long as you use the steel gear. Just make sure you measure the shaft diameter, ford made two sizes.. .467 and .531

Summit Racing has a GM style HEI distributor that works great and can be had for around 100 bucks. I used it on a 95 GT engine that I carbed and dropped into an 82 cj-7.
