Edelbrock uses an MSD dizzy w/ optical pickup with their proflow efi system. Coills can be of your choosing (I'm running a Mallory but once it pukes out I'll probably switch out to an MSD blaster). I don't think the dizzy matters either (especially in a bronco that won't see much over 5000 rpm), but it has to have an optical pickup and you have to know how to set it for a base reference (10 deg or something), no vacuum advance (comp. does that). I also have and MSD 6 ign box but you don't have to have it, it'll run either way.

I can get you the MSD part number from the dizzy this pm if you want it.

Kinda hate to admit it, but when I put in my proflow I did a bunch of other stuff at the same time, got in a hurry and wired my MSD6 box in backwards (+ to - etc.) and fried it. Took it out of the loop and ran for a couple of weeks with the dizzy and the Mallory coil only. Worked fine.

Signal from the dizzy goes to the ecu which times the collapse of the magnetic field at the coil (spark voltage). The MSD ignition box just modifies the signal from the ecu to make the coil fire more at low rpm. You can probably use the coil you've got as long as its robust. If it runs weak, get a new coil.

I run the pro-flow system on mine and have stuck with the MSD system. You already know that the Billet distributer comes with the Pro-flow injection. Most everyone as well as myself use the 6L ingnition box and I use the Small "Blaster" ford coil. I picked up the ignition box and coil right out of Summit Racings catolog. Good luck with the install. Mine has been well worth the investment.
