Didn't realize I come off as wacky :) lol
I'm just trying say that formula seems to do more harm than good, by that formula a 650 would be over carbing a lot of 440's.

I think most here would agree that a stock to mild (350 ish hp) 318-360 would do good with a 600-650 carb especially where driveability is of most concern, no need to go smaller and or to use that formula. The idea of velocity is making people too cautious a lot of times about carb head valve etc... choices.

I take it You have a 2bbl on the engine now? If You gotta buy an intake, the RPM will be a better choice IMO, leaves room for growth. A performer ain't no better than a stk. TQ intake, just lighter. An AVS/TQ or Vacuum Secondary carb like a Street Avenger will let You go larger, again with room to grow, without destroying fuel mileage like a Double Pumper.
As is, a 650 AVS or 670 St. Av. will do You fine, a 750/770 gives room for more cam etc.
Don't get too "bent up" about headers, You can get into the low 12's on a set of 1&5/8" heddmans, so big tubes ain't needed, Quality & Fit are more important to You....
