I have a 1986 M1028 with a 6.2 which is being replace with a 96 6BT cummins. The truck is apart and almost ready to place the engine into the frame. This will just be temporary in order to fit up exhaust, fuel, intercooler hydroboost, etc. I have been taking photos along the way I can supply to anyone interested in the swap. I am keeping the turbo 400 and changed the gears from 4.56 to 4.10s and will be running 255/85/16 tires which will lower the gear ratio somewhat. :tu:
