Need help with intake!

[Scrapla]

My car is almost done and ready to dyno just figuring out which intake tube to use. I want a 4" anderson (AF00112C). I have a 75mm accufab TB and a 90mm mass air. I called andersons and they recomend a 80mm mass air and thats what they design their "power pipes" for. I cannot afford another mass air, I need to make it work. He told me it should but because their pipe re routes the intake tube into the fender well it might make it to long with my 90mm mass air and filter which would cause it to stick out the bottom of the car. I need everyones opinion on what I should do, I have a tight budget and i'm at the end of my build and cant afford much more. My 347 engine combo calls for a 4" intake, what would you all do?
