Killer man!!
I did a 4.0 swap on an 89 BII I had, it actually got better mileage afterwards....
33's with 3.73 and the 5 speed I can average 21 on the highway.

Rear 7.5 locked for now, need to find a 4.56 geared 8.8 to match my other pig. I imagine it wont have any problems lighting up both tires, wet pavement may be intersestingits a lot different once you're looking down the other end of the barrel eh?
is your 8.8 open or L/S?my truck felt like a hot rod when it was an open legger- grabbing second and third gear on pavement![]()

The fronts have already been trimmed, couldn't even steer with 34s without them hitting badly. Rears still need a small touch of trimming.
So driving in the rain earlier (Because that's what washington is like in august) going around corners just putting along in 2nd about 1500 RPMs, slowly roll the throttle and it's spinning both tires and I'm goin sideways, took everything the 2.9 had to break em loose in 1st, 4.0 does it without thinking twice in 2nd and this tranny is higher geared. Here's a pic under the hood, still some wiring to organize but overall it's 98% done.
