Throat size of upper intakes

[95wanttobe]

From what I can read TF has some upper intakes with a larger mm size such as 90 or so. What is the standard size of say the perfromer rpm II or the holley systemax. 75mm perhaps, I can't seem to come up with the info. The sticky for flow rates seems to have expired on the board or I can't bring it up, thanks.

Only 5,000 more miles to go to get my 347 built. Hopefully I may get it done by new years. One day a week for a few hours is painful.
