That formula was wrong when it was developed. I know this is hard to hear, but it's wrong. Always was. Always will be.
Just like picking a carb by CFM rating. I'm sure if you look around you can find the Venturi size for your carb. If it's between 1.375 and 1.400 run it. Ignore CFM ratings and math that uses RPM/VE/displacement to pick a carb. You'll be undersized every time.
As an example...I'm looking at buying a carb that has 1.375 Venturi but flows 930 CFM at 20.4 inches of water. How do you explain that? It's because the shape of the carb is way more important than size.
That's what I'm saying to you. Skip CFM to pick a carb. Find out what Venturi you have and if it falls within the above, run it.
If it's a track only car, and you have the gear and converter for it, you can easily run a 1050 Dominator. Won't be nice for the street. But at the track it will be quicker.
