Stop Stop Stop!

Before responding to questions people should understand he has a 304 V8! So far SOME people have told him to pick up parts for the 258 I6! PLEASE DON'T DO THAT!

Jeep Hammer gave part numbers for the 258! They are WRONG! The directions are the same, but not the parts!

That distributor from Summit is correct. You want an adapter and cap for THAT distributor, not the I6.

PLUG WIRES
You'll need to be careful here. A Jeep 304 and a Jeep 360 use the same set. I cannot tell you which set because there are two different kinds of boot attachments for the distributor. My suggestion is to look at the plugs for a 1991 Grand Wagoner. My thinking is this: By then I believe the wider cap was standard and the wires should fit. CHECK FIRST!

That is why Steve posted the link for the v8 dizzy and I posted all the applications to show it can be from a lot of different models.

I see that. But they were giving part numbers for all kinds of stuff like adapters and plug wires too!

Thanks

That isn't correct. The cap was the same from '78 through the last FSJ in '91. If the Ford type cap is used, the Ford plug wires should be used. AMC plug wires will not be correct in any year AMC V8 for use with the Ford cap.

Thanks. There's the answer.

OP by now must be wondering what he got himself into!

CJput,

You're entering a world where you will want to keep a notebook of what you did to what on Your Jeep. What you're doing isn't rare, but what made life difficult is when auto part stores decided to put a computer on the counter and man it with snot nosed, pimply faced teenagers who only know how to fill out the template on its screen.

It used to be that a good counterman was worth his weight in gold. You'd tell him what you were doing and he was on to the program.

Using Ford or GM parts is not unusual. In fact Jeep did it. They outsourced lots of their parts. Some say Jeep Employs Everybody's Parts! You keep a logbook so you know which vehicle you "own" to imput into the computer to get your Jeep's parts.

Ooops, my bad also. I saw his list of parts for an I6 and didn't realize he had a V-8. Whatever Ford V-8 application you get the cap and cap adapter from, get plug wires for the same application. They are an HEI style terminal on the cap and coil end. If you are using the stock AMC coil you will need an adapter. Or you can just pick up a Ford Ecore coil.

So if I pick up a 78 or later dizzy for a 304 will I need to us the gear from the old dizzy or just run the new gear that comes as part of the Motorcraft dizzy?

The link I posted above from Summit is a direct drop in.

Thanks Asteve and the rest of you! your help is appreciated. I think all the extra work for the CDI system will be worth it over HEI from what I have read.
Here's where I am on the parts list for the 1977 304 Prestolite switch over:

1. Dizzy- Either 100-304891 from Summit or a Motorcraft from my auto parts store. Summit is drop in, if I go with a 1978 or later will it also be drop in? Will the gear be OK? If I order locally I won't have to mess around with shipping a core back to Summit.
2. MSD Street fire ignition (MSD 5520)
3. Cap Kit (MSD 8414)
4.Adapter plug (Jeep/Motorcraft dizzy to MSD CDI Module) (MSD 8869)
5.Wiring extension (MSD 8862)
6. Plug Wires- (MSD 3119)

Time to go to work?

No need to change gears. That's why that one was chosen.

CJput,

I thought I'd give you some visual aids.

I'm running a "Team Rushed" Motorcraft dizzy, with MSD module, coil, and wires.

Be advised, you may have to fashion a retainer clip to keep the cap adapter from spinning on the dizzy's housing.

Thanks Matt. I'm slobbering all over my desk! What a good looking engine compartment and 360! The visual really helps. I think I'm going to lock-n-load on getting my parts ordered. I'm also envious of your power steering but thats a project and parts search for another day.
Nice ride!
