Two schools of thought here, Bill.
1. Install a breakerless conversion in the stock Ford points distributor(the Crane XRI has a rev limiter). Other brands are the Pertronix Ignitor, Mallory Unilite, and Accell, I don't think any of those have the rev limiter.
2. Source the wiring for a Duraspark Ignition conversion. ie. the wire harness from distributor to module and module to coil, then purchase the ignition module and distributor from a parts store. No rev limiter there either.
None of these change the advance curve mechanisms, so you would need to recurve whatever distributor you used. There are kits with a selection of springs and adjustable vacuum advance cans, so it is available.
Hope I have helped some.

One more thought to add to Putt's comments. I went with a modified system that runs the 70's Duraspark II distributor (from the salvage yard or favorite parts store) but nixed the associated brain box and wired in a GM HEI ignition module for around $20 in parts and wires. There are instructions here on the site someplace, just need to search...

I havn't bothered changing out the breaker points dizzy yet: I've read complaints about the reliability of Duraspark modules, complaints about the cost of quality modules ($60 to $70 range). I've seen the page Mike G mentioned (lost the bookmark), if I understand right the GM module runs a full 12 volts to the coil, Duraspark does not. Hopefully someone else can tell me if that is fact-or-crap.
What has not been addressed is the second half of your dilemma, handling the secondary voltages. The reason for the big caps is that the smaller caps cross-fire with the higher output voltages. That kind of shoots you down with the room you have (BTW, nice set-up). I've read of some kind of off-set distributer or bushing to clear blowers and such-but there goes the budget.
I'm watching this thread, there's a lot to be learned here.
Good luck, Mike

I actually like the simplistics of the HEI unit. When going with the DSII system, you need to get the right box with the blue wire grommet, or you may end up with a unit that has emission curves built in... This was pretty much a wire in deal, mounted it on the firewall atop a heat sink, it just sort of hides there. The unit was I think $20 and I found the distributor in the salvage yard (looking pretty new on a trashed body truck). As far as the distributor width, the necks were all the same size, it the cap base and body that vary. The big caps were not used on the FE equiped motors, however, you can purchase a spacer for the wide head cap if you desire....

Not too sure about the box for spark control and rev limiting, The HEI unit is teh replacement for that or the DSII box. I'm not too savy on the electronics side of the motor, I just know how to get spark to the plugs... The unit is actually only the small (3-inches) 4-prong brain from the mid-90's vehicles, wired in from teh ignition swith to the coil/DSII distributor. I think you can see in my gallery under the progress heading that it looks all stock at the motor (of my old farm truck too).

ya i am planning on doing it also just cause its smaller and easier to sore as a spare but you have to build a heat sink but the hei module with a ds2 distributor i hooked one up on my buddy's bronco and he loves it here is a diagramn i made hope it helps [IMG]
[/IMG] And BTW there prolly is Gm parts on your ford anyway since they bought parts from each other rather than maufactung their own fuel pumps was a big one with for though all fords used to come with AC Delco (GM) fuel pumps
