i know how to figure out the CFM a motor needs but where do i get CFM ratings for TB's?

motor in question is a 408 with AFR 185's,custom cam,Spider intake(vicjr with elbow for TB and injector bungs welded in) ..those heads wont breathe much above 6200 with 408cu so figure that to be the max RPM..i am guessing in the neighborhood of a 75mm or 80mm..thanks in advanced..

BTW the dyno pull to achive the power that i build "my" combo after was used with a 750cfm demon
