06 H3 engine swap 3.5 to 5.3

[j & L]

Has anyone done this engine swap who can tell me what mods have to be done to make this happen. That 3.5 is a pile! If anyone can help it's greatly appreciated, or if anyone knows of a different size V8 that would be better or easier.
Thanks everyone.

Has been done a few times, only a few mods are needed. They can add up to $$ but the "mods" are minimal. The 3.5 has served many of us well, still on mine until it blows then the LS goes in.

I can't seem to find that thread? I need to know what I need to swap the a 5.3 out of a 07 Yukon to my 06 H3? Or what donor vehicle I should be looking for? Sorry to be a pain. Im so frustrated with this 3.5 it's been a nightmare. A money pit.
Thanks for any and all help.
