For what it is worth. I have never had a desire to replace a Carter BBD with anything else under most circumstances. I have had no problem with rebuilding them if it was needed, adjusted correctly they work just fine. I have built some quick I-6's using a stock BBD and have one stock one currently on the road that regularly gets 24+ miles per gallon and will run with current traffic conditions. Set up correctly with the vacuum lines hooked up as they should be they have never given me a bit of trouble and they pass smog in this state. Are they perfect? No! But they get the job done well. The basic problems I have found were with the vacuum lines, not the carburetors. They are also small, but that is typical of all American made I-6 set ups other than the Pontiac Sprint packages used a number of years back. I have reason to believe that they are specked out at 179cfm by Carter which is more than a bit small for an AMC I6 or anyone else's for that matter. For those situations where small was a problem my preference was then and still is to install a small Carter AFB and go for it. If that was not exotic enough I have gone the fuel injection route. I have yet to, but it is on my round-tuit list to built a turbo version of an AMC I-6. I would dearly love to beat up on Buick GNs. I have found that the advantages of not having to spend a ton of money on a carburetor that is no better, not having to cob up some kind of crude linkage and I have seen a few beauts , and for automatic applications not having to cob up some form of kick down linkage has more than paid for itself in pure lack of aggravation.
