Originally a 4.0 SOHC, over reved it in a water hole that was up to the windows, (almost made it out) put the body onto a '96 5.0 AWD and made some 2.5'' lift blocks at the same time, 31'' muds for now, just installed the beefy 5.0 with the torque monster headers, got 25 miles on it now. Next is the 4406 swap, then the dana 44 swap with maybe 36's? Also looking to buy a winch and make a front bumper with a reciever, then mount the winch to a plate that I can slide in the front or back. I drove it bone stock for over a year before deciding to make it a toy, always loved these Expo's!
