Default F.A.S.T intake ?

was wondering if the only difference between the F.A.S.T 90mm and 78mm is the top half. i have a company who will sell me the intake. but says the top is a 90mm and but the bottom came from a 78mm. he says the bottom of the 90mm and 78mm are the same. can someone verify that for me?

They are the same. That is why you can buy certain sections of the manifold alone from most of our vendors (Thunder Racing is the one I know) in order to upgrade your 78 to the 90.
