Engine swap idea

I have one of those I6 in a 2000 Cherokee. It's a peppy lil engine as is. I've had it since it was practically new and its still going strong with over 200,000. The trans is going strong too. It is pretty tall though like others mentioned.
The transfer case is what determines the 2wd or 4wd? So I'm confused about the earlier comment on finding a 2wd trans?
Personally I think if you're gonna stroke it, you might as well just go with a V8. Find a Dodge Ram 5.9L/360 or something.
Just my $0.02
Good luck!
