A couple more comments:
The RACE 4575-AAA Dominators only had 2 corner idle on the Primary Metering Block.
The secondary metering block was like a early 3310 4 bbl (780 cfm carb) and the metering block was not machined for a power valve.
Racers assume minimal idle times and lots of WOT TIME. The early carbs were 1150 cfm.
A famous Ford Racer was 7 mph faster in speed vs the field with his 4575-AAA carb.
