After Market Carb

As an FYI Money Pit, the BBD 2-barrel was the early super-six factory stock carburetor

The BBD was the only Super Six stock carb.

However, I personally would not go near the Holley 2280 that was the later Super Six factory equipment carb.

No, sir. The 2280 was not factory-installed on 225 engines. It was offered by Holley as an aftermarket replacement for the BBD. It's got several design and build advantages over the BBD: the 2280 is made of aluminum instead of pot metal, there's a very wide range of main jets available for the 2280 but not for the BBD. They're both good carb designs as configured for Chrysler Corp vehicles (the Jeep/AMC BBDs are different and have a bad reputation); whether a BBD or a 2280 is better for your Slant-6 is down to the condition of the particular carburetor(s) in front of you. New old stock BBD versus new old stock 2280, tough to go wrong either way assuming both carbs are configured for Slant-6 applications. New old stock 2280 versus Chinese knockoff "100% NEW!!!!!!!" BBD-shaped trinket, the 2280 wins with both throttle plates tied behind its back. Basically-sound used 2280 carefully reconditioned versus basically-sound used BBD carefully reconditioned, another tough pick.
