We'll agree to disagree. AFB"s, IMHO, are fine as long as you don't have to open it up.
In 64 while I was in the Marine Corps a good buddy stuffed a Caddy 331 in a 57 Del Ray and he was having a devil of a time trying to get it to run right. It had a Carter AFB that was all messed up. another good buddy who was somewhat of a carb guru at the time spent an hour or so trying to get the floats adjusted. It was a lot of trail and error but he finally had it running fairly well. later I ran him with my coupe, 36 5 window running a 301 with 2-4's and smoked him pretty bad.
Moral of the story: with a Holley all that would have need to be done was open the sight glass on the front fuel bowl and adjust from the screw on top, 5 to 10 minutes tops.
