Here's one that would be very easy to work on and could be used indefinitely as a FE carb.

Motorcraft 2150 Carburetor
Almost nothing to go wrong on the carb and very easy to tune. I'd put an electric or manual choke on it instead of the heat tube choke, otherwise it looks ready to go. You may even be able to buy one of these new from your local parts store. My 1968 galaxie came with this carb, so I'm pretty familiar with it. You would need the four to two barrel adapter as well.
