Hi. First, it isn't a V6, it's an I6 (Straight 6). Second, my car is currently running an original Autolite 1100. But I am going to change that soon.
If money is no limit on what your getting, then get Pony Carburetor's new 1 barrel carburetor. They have redesigned the internals and given it annular discharge like the 2 & 4 barrel carbs have. They have improved the 1 barrels performance. It usually runs about $400, but it is well worth it, that and a concours rebuilt one is about $600.
