What would my rpm's be with a 3.73 & a 4.10 at lets say 40mph in 4th gear. For a naturally asp car which one?

I have 4:10's and at about 40mph in 4th I'm looking at around 1200-1700rpm's. Thats just a round about estimate. Although at 40mph in 5th I'm looking at just over 1000-1200 rpm's. At 60-65mph I'm also looking at around 2000-2500 rpm's in 5th. Hope that helps.
