Ring and Pinion...Is more better?
So the plan is to swap in 4.88 gears both front and rear. My 90 came stock with 4.56 and 2 pinion, according to off-roads chart. So when doing the swap, can I go from 2 pinion to 4 (which seems to be more common for the V6) or does it not matter.
I run 32's with the V6, manual tranny and stock 4.56 gears. I can do 70 mph @3000rpm.
I want 4.88 gears to increase power and probably to accomodate 33's in a while. Would doing this swap dramatically change rpm's at speed? Or would it be best to wait for the 33's to swap gears?

I think 4:88's is just right for 33's with a manual. With that said 4:56's are certainly livable . If you must regear, I would find a bad rear (3rd) and rebuild it and find a wrecking yard factory 4:88 front . Then sell your 4:56s to recoupe you cost. BTW I don't think this is just offroad tech.

I agree with Adrian, that small a change probably won't be worth the expense unless you can find complete thirds for sale for cheap.
In the early years of the V6 diff (up to about '91), 2-pinion V6 diffs weren't uncommon at all. AFAIK, '88 V6 diffs were all 2-pinion.
Also, to clear up a little possible confusion, the "pinion" in "ring & pinion" is not the same "pinion" in "4-pinion". They are entirely different gears. In order to swap from 2-pinion to 4-pinion, you have to get a different carrier. Swapping ring & pinions does not (usually) require this.
