Hey guys, I was wondering how hard it would be to install a 2004 Grand Cherokee 4.0 into my XJ. I just had a 04 Grand Cherokee engine rebuilt and now that I have decided to forgo the Grand build I am wanting to install the motor in my XJ. I know the motor mounts are different but luckily I work in a machine shop so fabricating mounts is not an issue, I have made many. I will only be using the block. This motor does have a Tupy head but I have a 7120 and want to keep it. The only thing I plan to use is the block and the newer intake manifold. What issues will I come across. I have put many non Jeep engines into Jeeps, those where complete engines though, not parts of engines miss matched, rebuilt entire Jeeps, and turned many wranglers into tube rigs. I can do the work, just pretty much need to know if anyone has knowledge of this swap and knows the mods that have to be done and whether it will even work without a total transformation and if my head will bolt to the block, if the newer style intake will bolt to my head, and if my tranny will bolt up? I have a 01 AW4. Thanks in advance!!
