Finding the best ratio

[rfoutch]

I have searched the Fourm and can't find this, though I am sure it has been asked before....

I am thinking about a new trans for my thing (181) and need it to work well in the following conditions. My question is gearing, as my driving will be 80% on-road 20% off road (though I get kinda crazy off-road).

I will be stuffing a 2.0 914 type 4 in, so this will be to mate with that power plant.

What would be the best R&P and Final Drive would like to squeze the best highway performance without loosing to much off road performance.

With that in mind, what would be the maximum tire size, lets say 15X6 rears. Would like to run the tallest tire I can get away with. I will be running 2X3 (two inches longer, 3 inches wider) trailing arms. Also, will be running a 3" body lift.

So I guess I am looking for a high bred freeway flyer and a nice offroad trans?

Suggestions?

Sounds like a pretty cool project! Bus trans with 4:86 or 4:57 and 33" tires should do the trick. That type 4 motor would have no problem with this set up.
