That engine would be a lot of work and some redesigning. It would be somewhat easier with a 4.7, but even then not ideal. Your best bet would be to find a donor jeep, one that has a messed up body but good running gear and just transfer everything from the donor rig into yours then scrap out the what's left of the donor jeep.

Right well could i put a bifger engine in mine? Im just not aurenif everything would fit or belong there.


Bigger engine is more cost, then some customization, new ECM, brakes, maybe trans, and rear end, etc. Then you'll have over 10K into a Jeep that is worth $3K. Listen to tennis shoes, it is sound advice.
