a Concord with a 258

That may have the piece that you need, if they are interchangeable between the distributors. I know Eagles with the 258 used Duraspark. This Concord might too.

It did. 82 GL that looked like it had been on the receiving end of a .50 cal. Diaphragm was good and put it in the dizzy.

I’ll be watching your adaptation. Should be interesting and has me curious. 

I got it all done and running pretty good tonight. I gotta get the transfer case back in tomorrow and I’ll take pictures of how it’s all set up. For just eyeballing the distributor in, I think it’s actually set in perfect, revs are snappy and there’s no backfiring or missing at high rpm’s.

Interesting…I wonder how well it will do. I know for my 2.5L XJ coupled with the 3.55 A35 out back, it is a dog and sometimes has some trouble revving with the carb but that might be because I have the carb adjusted for AC compensation.

Got the transfer case all reassembled after having to install a “long” shaft in leu of the “medium” shaft that it originally had. Not a terrible job, but having to tear the entire case down does get a little annoying, but at least it’s pretty simple and I have it down to an art now, but luckily I had the “wide” bearing in a parts case or else I would have been stuck for a little bit.

Well, as much work I’ve put into the auto & Duraspark conversion, a Comanche near me is getting parted out. 4x4 AX-5, so I think I’ll be manual swapping it, the 2.5 will be much happier that way.

Every time I’d go to put it into drive, it immediately dies. I can bump up the idle so it runs, but in park it idles at like 2,000 rpm, + it just doesn’t run quite as well as I’d hope it would.

Got an AX-5 to slap in, just need a flywheel/clutch

Got the swap somewhat finished up. Test drove it and it runs amazing! Too bad it was dark & 8° or else I would have videoed it.

To update, I’m planning on selling this truck sooner than later once I get a title put on it, but in the meantime I finished the swap all up and even got the interior looking somewhat decent with a shift boot & knob from an S-10

…and it’s gone! Hate to see it go, but don’t mind the extra green and garage space. Good little truck. Gonna miss it.
