View Full Version : Which ignition for '84 Bronco w/351W?
07-31-2003, 11:17 PM
I'm building up a 351W from a short block and have installed Edelbrock aluminum heads, manifold, cam and carb. I'm wondering what MSD ignition system (distributor & controller) would be appropriate for my vehicle? It's mostly a daily-driver, with a little extra low-end for towing. Some very light off-road use is likely. Do MSD controllers replace the existing OEM ignition system? Sorry about asking such basic questions - but I'm a real newbie at this!

Yes the MSD Unit will replace the factory ignition, although there are several options that you can go with, depending on the set up that you are going to use.
1. Using a Ready to Run Distributor, PN 8354 Ford 351W, w/vacuum advance.
2. If using the Victor Jr. Intake Manifold, we offer a distributor for this set up, PN 85805 Ford Billet Dist. for use w/victor jr. manifold
If not using victor jr., you can use the PN 8584 Ford Billet Distributor, or if running into clearance problems w/any other type of water neck of manifold, we offer a small diameter, PN 8578 Ford Small Diameter, or the PN 8478 Small Diameter w/vacuum advance. All of the following distributor part numbers will require an MSD Ignition Unit, like the PN 6200 MSD 6A, PN 6420 MSD 6A-L w/rev limiter or the PN 6470 Off road Ignition.
As far as coil, I would recommend using the PN 8207 Blaster SS Coil, for any of these applications.

Perfect! That's exactly the kind of info I was looking for... Thanks!

One more question... Based upon your suggestions I'm planning to go with the 8584 dist. (I'm not using the Edelbrock Victor Jr. intake), 6470 ignition, and the 8207 coil. What will I have to do to my existing wiring harnesses? Are there adapters that will make the existing wiring compatible with the MSD components?

When using our complete ignition system, your factory harness is removed or tucked underneath to where it is not visible; the only wire that you will need is going to be the switched 12 volts ignition wire.
