What carb for my 340 build?

I know this is an older post, but I'm keen to find out which carb the PO used in the end.

I have a mild 340 with a Comp XE274H hydraulic stick, my car's a 67 Barracuda, 4 speed with 8-3/4" sure-grip 3:23. I plan on running an AFB competition series 750, what do you guys think about this carburetor for this application?
So you already have the Carter style 750?
If you do, run it it’ll be good.
Otherwise, a Holley would be just fine as well. A bit better in tunabilty. Something like a Brawler.

A 750 will shine better on the top end. I wouldn’t go past a 750.
