Please stay away from (any) rebuilt or remanufactured carburetor - unless you know the shop (or person) rebuilding your existing unit. The chances of getting a good (to decent) one is slim to none (or, in other words,
extremely high chance of getting a "sub-par" unit). If you perform a search on our forums for my name and rebuilt - it will explain why I feel this way.
Question: You appear to be looking for a Carter BBD - but is it for 318 or /6 (they look similar but are completely different)?
Next question, are you keeping the computer controlled carburetor or moving away from computer controlled?
I don't care much for Chinese auto parts - but this is an exception, if
moving away from computer controlled:
Electric Carburetor Bbd High Top Carter Style For Dodge 273 318 8 Cyl 1972-1985 | eBay
This is a new Carter BBD repop (or knockoff). I have purchased a pair and other than needing to set EVERY adjustment to specifications (they come way off) - they seam to be reliable.
I hadn't seen a computer controlled BBD knockoff - yet.
i currently have one on my '86 Fifth Ave 318 2-bbl (which originally came with a Holley 6280 computer controlled) with the computer on side of air cleaner. The computer is controlling spark (like normal) and is sending commands to the carburetor - but sense the non-computer controlled carb is not plugged into anything, the computer appears to be happy. It has been this way for eight, or maybe nine years now? (I can't remember).
If you get one of these new repops, take it to someone to get all of the factory specifications set correctly and it would work great. If you don't know anyone, have it sent to me. I'll get it set correctly and will send it back to you (for the cost of additional postage).
In my opinion a stock Carter BBD (either computer or non-computer controlled versions) are better than the Holley 2280 or 6280 versions - but that is only my opinion.
