Engine Swap for xj?

I have a 98' XJ with about 88k miles on it. Its in good shape but i want more power out of my jeep. I was wondering if an engine swap could be done. Does anyone know a good size engine (preferably a V8 or something big) that fits an XJ without any major problems. Please let me know if you have any Input/Info you can give me. Thanks

Thats a good one....lol. if anything..maybe the 5.2 from the grand..but thats about it. Your nuts doing anything else with that.

If you do the swap I need a 4.0 engine, I blew mine. Email me at [email protected]

Theres nothing you can put in there that will be worth the effort. Have you looked under the hood? Youve got to have noticed there not alot of room. Sure, you can shoehorn just about anything in there but it will be major problems.
If you really want to turn your XJ into a racecar (which its not designed to be) there are stroker kits and superchargers for the 4.0.
Better yet, just buy a used Grand Cherokee (ZJ) with a 360 in it and have a ball.
