Back when Federal-Mogul bought the orig Carter Carb Co out of bankruptcy, they chose to break it up and sell the parts rather than seek to revitalize it. At that time in the earlier 1980s or earlier, Carter the company was "over with", so to speak. No new products, just "old stuff", with the newest being the somewhat troublesome ThermoQuad 4bbl. "Weber" bought the company and sold about TWO carburetors, both fit Chevy 327s as I recall, as OEM carbs for the repro industry. NO Chrysler carbs.
Then Edelbrock bought the rights to the AFBs and went from there. Allegedly Edelbrock improved some things (possibly in the adaptation of the molds and such), it was claimed. First carbs were more universal than not, BUT they found a home in the Mopar community! And some of the '60s Chevy people, too. After they were doing well with the AFBs, I remember being at Mopar Nats one year and hearing a conversation that "I wish they'd do an AVS", as the AFBs only went so far with their use by Chrysler. I understood the sentiment and sent Edelbrock an email that they should consider doing some Mopar AVS carbs,too. When the first word of the "new" AVS came out, I was glad to see it (a few years later), but was underwhelmed to see that it was a universal-fit GM carb, basically. If they'd done a 625 and 750 AVS for a 1970 model year application, that would have been great, but that was not to happpen.
Seems like I remember hearing that some of the Weber AFBs had quality issues. Which I hated to hear, but as they were Chevy AFBs, not a big issue to me, with just two part numbers at that time. The Weber AFBs were a short-lived situation, that I know of. Perhaps others might add something to the story?
Enjoy!
