Eric,
I have a 3.5 rearend in my BJ8, which has a stock engine and 22% O/D.
Starting from stopped requires a little more finessing of the clutch to
prevent judder, first and second gears are more usable for the most part
and hill climbs are a wash (hills I used to lug a little in third I now
take in second with more revs and more torque on tap).
Overall, the 3.5 is an improvement in drivability, esp. on the highway
but perhaps not on a short track (I wouldn't mind a 28% O/D, either). I
think a stronger engine like yours would be even better.
