Alright. Here's the situation. I have a 1991 245 b230ft swap with an AW71. There is a 94 940 n/a nearby that I could get drivetrain parts from. It has a 4:10 rear diff and should have a G80 and AW71L as well but I forgot to look when I was under it yesterday. There is also an 89 760 locally that I haven't checked out yet but it seems like it may have an LSD.
I've sifted through threads for two nights and I haven't found definitive answers for a few questions. I've found various threads that say which years/models have different ratios and diffs but even those are conflicting sometimes. There also seems to be conflicting experiences for people. For example one thread someone said the G80 was unpredictable in turns and loud. I obviously don't want the back end to fly out from under me when turning in rain.
My ultimate goal is to ditch the open diff for traction purposes, improve acceleration, and improve mpg on the highway. I know increasing acceleration and mpg generally don't go together well, but thought there might be some combination of AW71L, gear ratio, and locking diff that could do the trick.
