Default 90 mm MAF

HI:
can anyone tell me if there are any 90mm Maf available for gm cars? I am planning to install a Ls2 in a c5 corvette i have a 90mm ls2 tb and ls2 intake. It would be a restriction if i install the maf from my ls1 engine which i beleive is 78mm. I have heard that the maf in ls2 is 85mm. can anyone help?

I believe the sizes out there beyond 85 is 100mm which you can find at TSP. (http://texas-speed.com/shop/item.asp...d=914&catid=75)

A later year C5 MAF is fine if you're staying with a stock displacement LS2. It's 85mm and will support up to 500RWHP.
