possible carburetor swap

Good info here gang. Thank you for sharing. So........ My apologies for hijacking this discussion, but I'm trying to figure out the best set up as well, for my 73 /6 225. I have a brand new Offy 4V aluminum intake and am unsure of the best carb to use on this setup. I understand the need for opening up the exhast to breather better, etc. Just not sure of which carb will be of best use for me. Daily driver, no racing involved on my end.
