Hello,sorry for the late reply,the truck is powered by a BB chevy major mistake(cant fit a air cleaner and cab gets too hot)and a th400 with a dana 70 in the rear.
I cant put smaller wheels because it is too low as it sits now,I would like to go to air bag suspension to get a better ride.here are some pics.
