efi to a carb dist

About the only factory distributor you'll find that's set up for use with a roller cam (steel dizzy gear) AND a carb'ed setup is the '85 Mustang GT with manual (T-5) transmission. You must specify manual transmission at most parts houses because the AOD cars in '84 and '85 were non-roller motors with CFI instead of a carb. Otherwise, there are some aftermarket distributors you can use that would work with a stand-alone ignition setup, but they will cost you a lot more and not really gain you anything in terms of performance.

From there, you can grab a Duraspark ignition off any older carb'ed Ford and use that for a stand-alone ignition (doesn't need an ECM, just the Duraspark ignition box and related connectors), or you can possibly bastard-rig an HEI ignition module off a GM to work. Do a search on Yahoo for "CFI to carb conversion" and you'll find an article on there with all the necessary schematics and part numbers. (It's a really straightforward hookup, only about 4 or 5 wires involved.)

The hot setup if you have the cash is to get one of those HEI conversion setups with the ignition and coil all built right on the distributor. It makes for a super clean and super easy installation.

Don't forget "super-expensive."

I'd like to plug one onto my '84, but I don't wanna blast away that much dough on an ignition that won't gain me anything but ease of installation ... and since a Duraspark or GM HEI isn't that hard at all to wire up, meh ... can't justify it, myself. But the option's out there for anyone with the cash.
