Went ahead and grabbed a set of 3.23s.. I think I can deal with them. Previously I was running right around 2600 @ 70 with 2.7s and a 26" tall tire (lockup wasn't working right) and it didn't bother me. Now the trans is built up a bit and the lockup should be golden. So I should be in the same ballpark with the 23s
the math with a 225/70/14 (26.4" tall) no slip (lockup) and 3.23's works out to 2900 RPM for 70MPH. it's a ford rear, right? I would've gone with 3.08's, would've got you a cruise RPM of ~2750.
