Everyones been great in giving me assistance so I thought I would throw this out there, for some more help.

Many Many years ago, I purchased a Holley carb from a guy who had this sitting stored away in a box for over 30 years, give or take. I was going to install it on my 65 fastback but I think the carb is for a bigger engine, plus I am trying to stay close to original.

Figured there have to be some carb gurus on here that can tell me what exactly and I have and what its worth if anything.

It has a metal tag on it that says, Motorcraft DOPF U A 3612

Stamped into the back part of the carb is, DOPF-9510-U, LIST-4548-S, 372

Best I could come up with is a Ford Service part for a 302, 390, 428, 429 Engines w/Auto Tranny. I found this on the Holley Carb Master List.

This is a pretty interesting carb in that is still has all the original markings on it, which look like they were stamped on by an ink pad. All the DO NOT TURN stickers are still in their original locations with the wax (Green color) underneath. Other then a tiny bit of rust on two screws, and being dusty, this thing is in excellent condition.

Anyone have any more info on this and possibly the value of this? I can take pictures if anyone would like to see it.

Once again, I appreciate everyones input in helping with my Mustang.

I've had a Holley List 4548 on my 289 for more than 15 years and it's still
going strong. It's basically a service replacement for 289 A-code
(Autolite 480cfm). It's a 450cfm carb like silverblueBP posted, however it's
a Holley 4160 not a 4150 (as indicated by the rear metering plate).

If having a busted overflow doesn't bother you, it'll be OK. It's the Service Replacement for the Ford 4V carb, and IMHO, is inferior to the 4100 Autolite in every way. There is nothing original about it, it was never used as original equipment. It's Ford's replacement for the earlier factory carbs, after they stopped making the 4100. It's unlikely to be "too big" for any engine, since it's rated at 450 cfm, while the 1.08 4100 was 480 cfm. That makes it one of the smaller 4V carbs.
