I have tried to research this time and time again before my 6.0 pulled the pin on the hand grenade. The time has come to replace my 2006 6.0. I know the 6.4 uses the same 5R110 trans and is nearly the exact same size dimension wise as the 6.0. I can NOT find a single person who has done this as it seems way too easy to do. The 6.4 uses the exact same suspension as the 2004.5-07 superdutys, so all you need are the 6.4 motor mounts, bell housing(front case) is the same, so theres your trans and all controlled by a 6.4 harness. Would I have to swap the clusters out and thats it??? Seems easier then a cummins swap and more power from a stock motor thats more reliable then a 6.0.

Lets hear some feedback... I know a lot about swapping in a 12 valve p-pump and VE pump but really want to do the 6.4 swap if I could.
