Default what donor engine do I need?

next on the build list is a 6.4 hemi swap into my 2012 JKU. I have a 3.6 with W5A580 auto transmission. need to know what vehicle i need to pull the 6.4 out of, that will bolt up to the W5A580 transmission.

Have you looked at an LS swap? The feedback on those seems to be more positive and they are lighter. Also seems like an LS can be done for less money.

I could be wrong, but I'm sure you need a new transmission when you do a Hemi swap...

the newer 5.7 and 6.4 both use the w5a580 auto trans in various vehicles. the same trans thats in the 3.6 unless im mistaken. im pretty sure i read that this transmission mates right up. would really like someone who knows for sure to respond. dont need opinions, "maybes", or "i think..." would really just like someone who knows for sure what engine i need and what transmission i need IF in fact i need a new one, which im almost certain i do not.

With that being said, call DODGE.

yeah why would I ask a question about this on a Jeep forum? thanks for trolling and again, thanks for the nonsense that in no way answers my original question. its really not that much to ask for. for the guys that have already done a 6.4 swap, what vehicles and what year ranges did you pull from that will work with the W5A580 transmission. dont need write ups or price quotes or how to's. just need to know what engine will work with this transmission. i dont need advice on LS swaps. i dont need a review for AEV, BOR, or Bruiser conversions or JSS. if you want to PM me to tell me im a douche or whatever go ahead thats fine. but the point of this forum is to ask questions and to learn from each others experiences and share knowledge. so i personally dont think im "out of line" when i ask a question that i KNOW can easily be answered by the slew of forum members that have already done this swap.

so with all that said, if you can help that would be awesome. if you cannot then thank you for your opinions, comments, and conjecture but it really isnt needed or wanted for that matter.

lol says the guy that joined the Air Force. this forum is a joke. there is not a thread on here that doesnt take 10 pages of sifting through sh!t to try and find anything related to the original post. its simple really. when someone asks a question I KNOW the answer to, I respond with an answer to their question. it makes things easy and it makes things easier to search.
