I know this will probably get bashed, but oh well.
I know flow #'s aren't the whole story,but all the small blocks I have checked I can remember off top of my head 450,416(1.84/1.50 or 1.72/1.50)for 305 624,882 350(1.94/1.50) for 350 flow #'s are so close together AT .400'' LIFT AND BELOW that it wouldn't matter which one you used. about 165 cfm @25''@400(.388'' using lift/diameter ratio)is what I see on a SF-600 on those castings.
