Re: 1978 full-time 4x4. Is a 700r4 worth it?

I inputted those numbers into a RPM/Gear ratio/Transmission calculator and it said for 1600RPM @ 55MPH I would need 4.10 rear end gears with a 700r4.

Wouldn't that "lug" the motor? I mean, this is a typical speed I would drive to work so it is ideal to make that speed the most efficient.

If I put 4.56 gears in, it says that I will run 1750RPMs @ 57MPH. That seems better. What do you think?
i wouldnt think so. my 01 would get in od at 39 mph. was about the same at 55.
