Rpm's?
About how many Rpm's would a 5.0L mated to a E40d have at 70mph?
With a
3.08 ratio:
3.55 ratio:
3.73 ratio:
4.10 ratio:
If I went from 3.55's to 4.10's, would I lose 2-3mpg's?

Assuming 29" tires:
3.08 approx 1840 RPM @ 70 MPH
3.27 1950
3.55 2120
3.73 2230
4.11 2460
Can't help w/mileage, but when you're driving in traffic or hauling a load, any of them except maybe the 4.11s should beat the 3.08s. Unloaded on an open highway, the 3.08s should win, but so what?
