No clue, but ran a fleet of 5.7's from 2006 through 2015. Garbage! Everyone of them had valve train issues centered around lifter/cam failures. If the 6.4 has the same valve train...hard pass.
we have some 6.4 in our fleet and theyve done very well. the entire trucks has done very well if you want the truth. theyre around 100k with many thousands of hours idle time.
vehicle longevity or lack there of can largely be traced back to the drivers/owners. if you beat it into the ground no truck will last long
I've had both and agree with what the videos show. I also live in CO and drive the mountain passes frequently. The 6.2L was way better towing in the hills than the 6.4L.
Look on Youtube at the Gauntlet pulls of the 6.2 versus the 6.4. 6.2 blows the 6.4 away.
But that was before Ram started putting the 8 speed ZF transmission behind the 6.4. By all accounts the ZF transmission really improves the 6.4 towing experience.
The 89 recommended vs. 87 octane is a little overblown IMO. Our 7.3 trucks, per the owners manual say that 7.3 s designed to run on 87 "but for *best* overall vehicle performance , premium fuel with an octane rating of 91 or higher is recommended." (pg 179). So to get the best performance in the 6.4 you run 89, in the 7.3 you run 91.
The big thing for me when I was cross shopping HD gassers last year was MDS. My 19 1500 5.7 had MDS, and while not intrusive, it sounded like I had an exhaust leak when engaged along with a resonance. The 7.3 has no MDS and no auto stop-start...yet.

So Ford designed their new motor to run best on the most expensive gas?
