Converting a 1985 LR 90 from 4Cyl to 8
I was wondering how involved it is to swap a 4.0 into a 1985 L/R 90. I have the 2.5 gas motor that came in the truck and would like to swap a 4.0 that has a carb and an Lt77. My truck also has an LT 77. The truck also has A/C. I assume that it wouldn't be a strait one out, one in swap, but want to know if it will require major surgery.
