"Do the math on the gears.. It didn't. 4K rpms is what it was running in 3rd at 65 to hold speed, but not accelerate. "
I did do the math.
The ECO makes it's max horsepower at about 5200 rpm. The 6.2 at about 5600 rpm.
The Eco near the top of the hill was in 3rd gear. With the 3.73 the ECO will turn about 4000 rpm at 65 mph.
The 6.2 with the 3.42 would be in 4th gear and will turn about 4000 rpm at 65 mph.
But the 6.2 was able to accelerate more than the ECO when both were running about 4000 rpm.
It is obvious the 6.2 was able to make more horsepower.
