Is that an easy swap? Or the electronics going to be a big problem doing this?
For example the new factory 6.4L has MDS right?
What would be easier and more cost effective, to upgrade to the new factory 6.4L or the crate 6.4L 392 motor?

MDS and VVT would be deleted. A 6.1L ported intake would be used. Then it will play nice with the pcm. This would be alot cheaper then the 392 Crate motor Mopar sells

What would be the expected performance gain from the 6.1L?
Any idea in the price range to do something like this?
Thanks!

Not sure on a AWD jeep about the same from factory 470hp 470TQ. Complete long block would be under 10k no core charges.
