Johnny,
You know the term you get more flys with honey. That's what's happening here.
You have 12 posts, rather than answering a simple question.
In your post 4 you answered part of your own question

It looks like only a BBD and a Rochester 2GC 2 Barrel small bore carb fit directly on the flange.
Perhaps your question could have been...
Does anyone know how tall a
Rochester 2GC 2 Barrel carb is, from the bottom of the base flange to to top of the air horn and to the top of the air cleaner bolt (air cleaner bolt probably is variable by application)
For the record... I would have had the photo I posted in post 25 to you in post 4 had you not gotten all pissy.
