With a stock size tire what is the mph in 4th gear (M6) at 7k rpm for 3.73 and 4.10 gears?

I tried using a couple calculators I found online, but the numbers seemed off. So I thought I would ask to see if anyone had some experience with this? Thanks!

 

115-125mph with the 4.10's I think. it's been so long since I had my 96 Trans Am.

Thanks for the help... I have made my gear decision.
