The engines are the same basically so you could just swap over the electronic parts to the 89.....
I would just swap over the 'engine' and leave the intake and exhaust headers including the fuel rail, distributor and parts and alternator from the 92 in there.

Ahh ok, good to know, thanks. I knew the ports were different but didn't know the headers were. So only the short block will swap then.
Man I got this 258 with a new crank sitting in my garage and an 88 4.0 getting tired..... Stroker, mmmmm......

I am thinking the guts of the 258 into the 4.0 block making it something like a 4.7 'stroker'. :-)
It would be worth it to just swap the short block for the OP then eh. Keep the head and intakes and swap from there down. Even if the head needed a valve job, that isn't much.

Old gray matter getting confused, sorry. Are you talking about your setup or what? I don't remember what the bore on the 258 is. Is the displacement difference only in the longer stroke of the 258 or does it have a different bore than the 4.0?
For the OP, he would want the '92 head/intake/exhaust plus sensors on the 88 block - with the '92 computer.
For your glass-tub and the eng> I am thinking the guts of the 258 into the 4.0 block making it something
Sure can't, Bill. I've never laid a 258 head alongside a 4.0 head. You can see the difference between the 88 and the newer HO with the vehicles sitting side-by-side but I've never looked at 258 that way. When I was looking, I had a line on a wrecked 91 XJ with under 45k on the clock but I was too new at this to really realize the power difference and figured it was more work than it was worth to swap stuff around. Looking back...
