Body Damage is Cool

I just picked up a 4.0L motor complete w/ manifolds out of a 94 XJ. Has the injectors, trottle body ect. If I source a
engine harness and ecu from a manual XJ of near the same year, will this head bolt to my 4.2L block? Whitch pushrods should be used? Cam? ect. I can hardline the fuel system and run an inline 40psi fuel pump. What would be missing? I have an edelbrock performer 500cfm on an offenhauser intake right now and it needs to be rejetted as I nearly die from the exaust fumes (I bought it this way) I can install an o2. How can I make the crank sensor work? I have a source for a BA10 bellhousing in a 4.0L TBI XJ if nessessary.
Any thoughts?
