How can I tell if my coil is a capacitive coil?
I wanna do this HEI/duraspark setup but i have to find this out first. anyone know?

no. Its a standard inductive coil like every other ignition coil out there.86 Lincoln Town Car (Galactica).

SFAIK, the main concern with type of ignition box is what it wants for a trigger signal (basically, which distributors the manufacturer says their box will work with). I perceive E-core coils (the sort that came stock on SEFI/TFI cars) to be basically the universal coil option these days, unless you really prefer a different style for some reason.
What ignition arrangement do you have in mind at this point?2012 Mazda5 Touring | Finally working on the LTD again!

not fully aware. duraspark distributor with an HEI module as for the coil, i was trying to figure that out.1985 Mercury Grand Marquis ls-302 CFI

why? The HEI module isn't really any better than the Dspark box, and it was not designed for external mounting. You'd be better off with a Dspark box or a Chrysler ignition module. Those were intended to live outside of the distributor. If you want to go HEI, get the full HEI distributor thats designed for a Ford motor, then you don't need to monkey with the wiring or figuring out what coil is compatible.86 Lincoln Town Car (Galactica).

Fiddlesticks, I didn't actually post the post I'd written, possibly because my mom called me seemingly out of the blue wondering when I was picking her up for her doctor's appointment that I thought was tomorrow but was actually this morning. Previously-entered text follows, but it's more or less along the lines of what Thain says.
================================================== ======
As in, four-pin Chevy HEI? I've done that, slightly involved but it works okay. Got the schematics off of some Bronco site, and I think I made some notes on here somewhere. I did develop reliability issues, though, so possibly I did something wrong - maybe the lack of a diode across the relay to prevent power surges on shutdown.
If you can find the cheap HEI distributors on eBay for about $65 like Bowman85merc and I did, that's a surprising amount cheaper and easier than first paying $95 for a reman DS distributor, then an additional $25 for the "good" Mallory four-pin HEI module, and then still having to wire everything up and screw the module to a heat sink and still have it looking cobbled together. Come to think of it, after paying for all the extra stuff plus the wiring, it's cost-effective even to buy the "nice" Ford HEIs for $130ish from Summit or Speedway Motors.
One thing to keep in mind if seriously contemplating HEI, I've *read* that Chevy HEI modules have issues over about 5000rpm, so I guess for an actual performance effort you should consider getting a "real" module like a Hi-6.2012 Mazda5 Touring | Finally working on the LTD again!

would i still be able to run it without replacing the solenoid and adding a ballast resistor?1985 Mercury Grand Marquis ls-302 CFI

No idea what that has to do with your starter solenoid .....Originally posted by Merc302 View Post
A Hi-6 is a standalone digital ignition box. It uses a distributor's magnetic pickup (as in a stock Duraspark distributor) for a trigger signal, and it uses that to fire the coil. The only thing that has to do with the starter solenoid is hooking the big red power wire to it, and the small red (IIRC) wire to a switched +12 source. No need to add any sort of resistors - those are for points and nothing else SFAIK.
As for the Ford HEI - as I said, I got mine on eBay. Looked it up and the seller was "fatrodder" FWIW. Wheelie cheap way to spark your engine. I also mentioned already that you can get Ford HEIs from Summit Racing or Speedway Motors. Would it help if I search for it for you and post links?

I can understand that. One guy who was on GMN all the time during college is rarely on now for just that reason, e-mails from work during lunch and hasn't bothered with Internet at home. I usually keep in touch with him by phone these days.
This Fatrodder eBay listing has the same title as the one I bought from. Looks like his price has actually gone down slightly ($50 now). Steel gear is supposed to be good for using with a roller cam. http://cgi.ebay.com/ebaymotors/SMALL...Q5fAccessories
No idea how that differs from the more expensive versions for $130-$170:
I also noticed this seller on eBay who's quite cheap, though he charges shipping so the total cost is nearly the same as Fatrodder. Looks similar but not identical to what I've got (four-sided bit on the shaft housing is what I notice offhand). http://cgi.ebay.com/ebaymotors/FORD-...item4cf5786b07Last edited by 1987cp; 03-18-2011, 04:12 PM.2012 Mazda5 Touring | Finally working on the LTD again!
