4.0 to 4.0 H.O. in an 88 cherokee

[bryan wheat]

I am wondering if anyone knows what kind of troubles that i would go through trying to put a 4.0 H.O. in my 88 cherokee. And if it can be done, does the tranny have to be changed. I took the motor out of mine after i blew it up and than some guy broke into my friends shop and thought that it would be funny to cut out all of the wiring under the hood.
