Re: [AMC-list] 82 Concord carb issue.

[Frank Swygert <farna@xxxxxxx>]

The Chrysler 318 V-8 BBD will fit, but you have to use the base from the Concord carb. The butterflies in the base of both carbs are the same, but the venturii inside the Chrysler carb are actually a bit larger, so you get a little performance increase as well (a little more air flow...35-50 cfm is all IIRC). As Andrew pointed out, you lose the choke. I think the top from the AMc carb will fit on the Chrysler BBD also, so you could swap that over too. Only difference is the center section IIRC. Otherwise you'd just have a manual choke, or no choke. If you live in Florida or somewhere it rarely gets under 40 degrees no choke might work...

I'd do the TFI upgrade (search for Jeep six tfi upgrade) and use an older model (1980 or earlier) control box. I just checked the 1980 and 82 Concord ignition systems. Only difference is that the 82 has a two wire connector going into the ECM. Instead of the Motorcraft box consider using a GM HEI module (search motorcraft HEI module upgrade). The Motorcraft boxes aren't as rugged, and it's just a bit of wiring. The GM HEI module sits in the distributor on GMs, but sits on the fenderwell when used with a Ford distributor. Just bolt it to something metal, and won't hurt to put a little heat sink compound (such as used in computers between CPU and heat sink/fan unit) between the module and what it bolts to. It's sealed, no concerns about water. It's also very compact and rugged, and will outlast the Ford/Motorcraft (or AMC branded!) boxes, especially in rough conditions.

From: Ian Coleman <ianc_97@xxxxxxxxx>

the carburetors shot and I want to replace it with one without the stepper motor. would a Holley 2280 or 6280 or a BBD from a Chrysler work????? Iwant to keep the 258 as it is  but do something with the carburetion
and not modifying the intake manifold too much i do intend to do the  module to distributor bypass and get rid of the computer all toghether.
