I think that maybe you could get the engine to fit with the factory steer linkage if you could modify the oil pan a bit. Obviously the oil pickup would need to be modified too. the 4.0's have an oil pump the is somewhat centered. I think it could clear the draglink with some mods. If you could swing that alternator so it is up instead of down. that might work too. you would have to make another bracket coming off the top of the engine though. All in all, I think this swap is very doable. Do you have any welding equipment and a saw-zall. Anyway, good luck. I like the inventiveness of this build. [I too was told that I was an idiot when I installed a 500 inch caddy motor in my 75 ford pickup] I like to be different. My hats off to you sir!
