Replacing a 4.0 with a 302?

I was wondering how hard it would be to put a 302 with an automatic in my '02 XLT? I'm sure it's probably been done and I was wondering how hard it is to get things to bolt up and what kind of transfer case to use and any other modifications? I think it'd be a nice swap....any suggestions?

Thanks!

By the time you got it done, not only would you have killed the value of the vehicle, you could have probably bought one with a 4.6L V8 already installed.

You have to look at the big picture when you consider a swap such as you are thinking about...It's not going to be as easy as you think. All your electronics, etc. are going to be different, and even the tranny is going to be different. One of two possible scenarios is going to take place...It's either going to cost a king's fortune to do if it's done right, or it's going to be a cobbled mess.

If you are serious about putting in a new engine, I would recommend building it first A few people have done it with 2nd gens, and they mount up fine, but it needs the different tranny. Not sure if anybody has tried it in a 3rd gen yet, though.
