YJ Engine Swap - 4cyl to 6cyl (Difficulty??)

How hard of a swap would this be. I know I'd need a new wiring harness, engine and transmition, which I could get. But the actual swap itself, would it be difficult if you havent done one before?

Im not sure how hard it would be to swap out an engine, i've never done one so i can't give you any tips or anything. However i did swap out a tranny, transfer case, front diff, and driveshafts out for the first time in my XJ and it wasn't that bad. I could only imagine if you have the right tools everything would go fairly easy for you. Good luck in your swap man!:clap:
