Axle ratio ???
Been looking at pickups lately (mainly the Ranger
& the Dakota), & I've noticed that you can get
different axle ratios. My understanding is that a
higher number means more torque (& thus, better
acceleration, & better take-off when towing), while
a lower number means less engine wear & better
mileage. Is that right? Also, is it worth the
extra money to get an axle ratio that is different
from whatever comes stock?

more. You can also get a 3.55 ratio, but I don't
know yet if that costs extra. I probably spoke
too soon when I said it would cost more. Thanks!
You are right on the money, 5-10% decrease on the highway if you are traveling light, but maybe not at all worse if you are towing, hauling, or driving in-town.
I am quit happy with the 410, since this is better mileage than my 94 Z71 and much more power and effortless towing.

I don't know how many RPM you're turning at 90 MPH but I wouldn't worry. In my '92 7.3L the top end was in the 97-98 range. In my '99 7.3L the top end is 91 MPH. It's all done by that f^&$@#* computer. Ford thinks that we shouldn't be keeping up with the LA-Vegas traffic ;-)

with the 90 percent hwy driving I do, I like having a lead foot once in a while. Although, maybe with the 4.10 from a dead stop, my gas mileage might suffer considerably more than the 3.73. I am going off of what previous 4.10 buyers told me they got for m.p.g. on their previous Chevys. 15-16 m.p.g with either the 3.73 or 4.10 is good. I know when I went from the 3.42 to 3.73, my gas mileage did not suffer one bit and I had much more off the line pick up.
