i hear of people going to very large jets in big cube n/ss engines using afb/edelbrock type carbs. i've always wondered about that and my thoughts were; has anyone ever taken the plugs out of the fuel passages and checked them for restriction/flaws/size? after all the jet is just a restriction device and when that gets reduced big time wouldn't that indicate a possible problem somewhere else? are the cams so large that they can't create a good pressure differential? is plenum volumes excessive?
