Towing Experiences 6.0 vs. 6.4

[hypoxia]

I have not spent a lot of time looking but haven't seen much real life reports of someone switching from the 6.0 to the 6.4, towing the same load with the end results.

I'm considering the switch & wonder about that. Anyone?

I did back to back tests with a 10k lbs trailer with identical 6.0's and a 6.4.

The 6.4 just towed better. Made the trailer feel about 2000 or lbs lighter and had a better ride.

All the trucks had about 2000 to 3500 miles on them, same year, same equipment and cab/bed configuration.

The 6.4 is an improvement for sure.

I posted about this last December, I believe.
