Thank you, makes sense. Maybe why MSD rarely kicks in on our Charger. It hits 8th so soon in normal or Eco mode that I have to kick it down a gear (can't in Eco, paddles and manual mode are disabled) so it's not borderline lugging at that 45-55mph range.

I’ve been on the waiting list for recall on the cam phasers for over a year. Add that to being without the Expedition for 8 1/2 weeks this summer due to no parts to rebuild an axle that failed at 30,000 miles, I’ll take my “chances” with MOPAR problems any day.

I have a 2014 with 3.21. You'll find the final ratio of a 3.21 vs 3.92 truck is exactly 1 gear apart.
i.e. A 3.21 truck in 4th is nearly the same as 3.92 truck in 5th, etc.
Empty, they're traction limited off the line. The 3.21 is faster as you're shifting less. Both will spin 1st gear to redline with a good launch.
The 3.21 revs low enough in 8th that MSD will never kick in, the 3.92 revs higher (equal to 7th on the 3.21), but MSD will kick in more often. If you get 33+ tires, then get the 3.92. Otherwise I feel 3.21 is perfect.

Id stay in the 3.42, 3.55 or 3.73 on how you drive. The 3.92 will not accelerate that much faster.
GM for what it's worth, with an Eaton kicker is the best strongest one used vs Dodge. Toyota gas an electric Eaton, iirc 4.10 gears, 10.5" r&p.they chew up fuel!
I dought you'll find one, but the GM / Dodge 3.xL diesels could be fun too. But have to admit, they are a bit shy HP of the gaz rigs. Plenty of torque.
As many have said, as have you, many ways too look at this, all are correct, ALL are wrong too!

I'm now surmising the results were from 2wd launches/traction control doing its thing, inconsistent data or inconsistent runs.

For how you drive, a 3.0-3.5 ratio would be best. The 3.9+ tatios just burn fuel on the hwy. IF you are like me, drive in the 0-50, 10-15% max at 60+ mph. Then lower gears make sense.

I have a 16 Ram 1500 Hemi with 3.21’s I don’t tow with it, but it move very well for its size!
As far as the MDS, it is very seemless. You have to really be honest in to tell when it kicks in.
FWIW right now, I just had a lifter start ticking. So I need to tear into that and hopefully the cam is still good! I’m a Chrysler Jeep Dodge Ram tech. So I know these things fairly well!

To reiterate the question in more simple terms, how handily will a 3.92 geared Hemi blow the doors off a 3.21 geared Hemi?
Apparently...it won't.
Wow!
To say I’m surprised would be an understatement!
Thank you for that!
Can’t imagine the tires making that much difference. They must just work as good with the higher gears!
That’s because the 3.92 truck had larger diameter tires. So in the end the ratios were very close.
