Can you grasp the difference between a spread bore design and a square bore design? Both can be rated at 800 cfm but have totally different metering characteristics.
Edit this is what I was answering
(Maybe just maybe that 360 doesn't use more air than that 650 already provides.)
It's only a 650 if your engine vacuum at WOT is around 1.5hg and if it was the 750 would be about 650 too just at a lower hg reading. Different carb sizes is about restriction (vacuum level hg) not air flow (cfm). If you can grasp.
Your headless rooster style of debating is interesting but is giving me a headache.
