Hello, I can not answer each and every difference, Actually not many but to answer you? the long blocks are exact same, same part numbers and both are interchangeable. If you go with changing engine? you need to swap out intake manifold and be sure sensors are in same locations. Other than that? short block, long block, heads, etc are all the same. You have to put them side by side and do some swapping over with some parts as mentioned

the reason I ask is I can get a used 06 Liberty 3.7l engine for about 1/2 the price of a grand Cherokee, I have the parts, as long as the long blocks are the same I can switch everything else ,
Jeep Mechanic: Randall C, ASE Master Tech replied 5 months ago

Understood. On my end I have lots of factory programs etc and I did all the research I could and my answer still stands. The long block is same part # for both, Engines as an assembly complete? are NOT the same. You have to put both side by side , swap out intakes and sensors to same locations . Long blocks? heads? short block etc? are in fact the same.Hope this helps
