3.08 ->3.73, what is 70mph equivalent to?

I used to have a 3.08 10 bolt and I got a whole new 3.73 rear put in recently. What would 70 mph with 3.73 gears and the same 26" tires be in reality? (appx is fine)

Yes, I know I need to get my speedo recalibrated but for now, I'm just curious.

Thanks for your help,

Erik

What kind of transmission, what gear?

or..just let us know what the gear ratio will be.

70 x 3.08 / 3.73 = 57.8, so let's say 58mph.

That's assuming the speedo was correct with the 3.08's.
