I finally joined this forum so I thought I would share some pics of my 89 Bronco II 4x4 with a Ford 144 4 cylinder diesel swap. I have already had it together enough to drive about 1000 miles, I am now removing the engine to put in another identical one that I am rebuilding. When I put the current one in I didn't know its condition and of course it's worn out (burns oil, leaky rear main, etc.) Yes it is basically a tractor engine with 50 hp at the crank but even with the worn out one I was able to get 31mpg with a top speed of about 65mph. I made the bell housing myself with help from the fab shop at a steel yard for about $200 (most of that being the $100/hr cost of having stuff cut on their laser table. I used a stock Bronco II manual tranny (mitsubishi FM146) with the stock clutch/slave cylinder and the stock diesel engine flywheel. The truck was an automatic stock so I also had to convert to the 5 spd while doing the swap (actually very easy on these) Once I have the engine out I will probably add some more pics of inside the bellhousing and the clutch etc.
