I'm sure this has been discussed several time, but what complications would I run into, if any, if I swapped my 4.2l 258 I-6 with a 4.0l I-6 from a early 90's Wrangler or Cherokee? Any info would be appreciated. (I tried the search and it did not work)

what part didn't work?

from what i hear, just swap the 4.0 head and all the EFI guts onto the 4.2 block, there's even kits out there
