(93' Cherokee XJ, 4x4) I wanted to swap out my 2.5 L, 4 Cyl. engine for a 360, v8 engine. A friend told me that I wouldn't have to modify the mounts if i swapped in the 360. Is this true? If so, what else would I have to change/modify to make this work? thanks.

To do a V8 you will have to modify EVERYTHING from the mounts to the tranny and the TC. Do a swap to a 4.0 I6, still a big mod but at least your XJ was built to handle it.
This ^^^^^.... if you are hell bent on doing a V8 swap. think about these:
1. Do you have shop/garage to do the the work
2. metal working tools such namley welder or access to these
3. fabricating skills or someone who does
4. last but most important $$ / Time
if yes to all these then go here: http://www.novak-adapt.com/

Don't let your friend help you with this project.
+1 on what others have said. This is a big job that will require gobs of custom fabrication, careful planning, and serious ability.

I don't want to sound rude, but if you have to ask, you shouldn't be doing this. This is a lot of work, trust me on that. You will also have to convert it all to the 4.0 nose and custom radiator too. Really not worth it.

Really, I have never seen that in the hundreds of XJs I have seen in the yards. All the 4 bangers I have seen have the early style radiator and cowl
According to the dealer I go to, they started making them the same in the late '80's... My '99 4 popper used the same rad as a 4.0... Only difference between my '98 4.0, and my 2000 4.0 and the '99 2.5 was the fan shroud(and motor mounts, but they just unbolt and bolt the 4.0 one in)...
