Default F final gear ratio is 2.937?

I just found out the Fj cruisers had the same size 8.2" final drive,has anyone ever tried changing the final drive?
I searched and found out the 4.2 had an early speed cut, but maybe if the ratio is not too aggressive maybe it could work?

Looks like it is.

You might want to search a little. This subject has been addressed a few times with many thoughts about different ratios, and even a few installations.
