225 /6's created equal?

There were several different carbs too. There are two different Holley 1920's. The Holley 1945 1 bbl, and the Carter BBS.
The two barrel Carter BBD was offered in the Super Six option.
There was a 1 bbl offered for the Feather Duster and Dodge Dart Lite that had some interesting calibrations to get the mileage up in 1976.
The Hyperpak option used a small Carter AFB. This was pretty much the only option that included a dual iron exhaust manifold sytem.
Overseas there were a bunch of different offerings for options. Some of them multiple carbs. That's all fuzzy. Look into South American, Australian and South African slant sixes.
There's a guy in South Africa tooling up to offer repops of the four barrel, and dual two barrel intakes.
Australia has several aftermarket offerings, but I don't know if they were offered as options for production.
