Dual BBS carb question

[DBRoadster]

Hey Guys,

I've got a BBS carb off of a '55 Dodge 1/2 ton and was looking at trying to find a matching carb to use as a dual carb setup. I've read on some other posts here that some of you guys were having problems with running rich? I thought these carbs seem to be good for a dual carb setup as it seems to have a slightly larger bore than the BB carb. One problem I have is trying to find a matching BBS carb. For one, this carb doesn't have and id #'s on it anywhere? Any input of running dual BBS carbs instead of the BB's? Pros/Cons?

Here is a pic of the current BBS carb I've got.

I had a pair of those on my fenton manifold when I bought it but they were cobbles up pretty badly and the linkage was very sketchy. So I bought another B1B and used those. I did not se much difference in important measurments between the series other than the fact that these were spec'ed when hoods started getting lower for the 53 and later body styles. the BBS was used through 59 on automotive flatheads. Don't know for a fact if they are jetted larger than the B1B.
