Engine/drive train swap on '93 Grand Cherokee

I am just looking for an assessment of the difficulty doing some parts swaps from one rusted out clunker ZJ to one in much better shape with the following differences:

The donor is a 1993 Grand Cherokee Limited with a 318 V8 and the QuadraTrak option. The body is very rusted out and I hit a deer with it some years back so the front end is different color with lots of cracked plastic parts. I believe the fuel pump is out of it since it will run if I feed gas into it but the body is do poor that I don't want to bother fixing the fuel pump. The recipient vehicle is a 1993 Grand Cherokee Laredo that has a straight six in it and has to be put into 4 wheel drive, high or low, with a lever. This vehicle though has an issue where the engine is blowing oil into the air cleaner, either a hole in a piston or dropped a valve, not sure. I would like to put the V8 from the Limited into the Laredo and also use the transfer case and QuadraTrac set up. Has anyone every attempted anything of the sort? What kind of difficulties might I run into? Or, is there anyone interested in buying two 1993 ZJ's for parts? Come and get em (northeast South Dakota) and the price will be right. $350 a piece. Junkman will give me $200 each.

 

Welcome! Wish they had some $300 GCs around here.....two to make one hmmm
