6.4L tq vs 6.4L Maxforce 7 in the International trucks
It is funny the 6.4L Maxforce in the int. trucks has a peak tq rating at 1400RPM’s vs. the 6.4l tt in the super duty at 2000RPM’s. This tells me that ford chooses to keep max tq at close to 2000rpm’s for drive train durability or for better performance.

As for your drivetrain durability point- not so much an issue. Engine manufactures have been limiting torque in lower gears for just that reason for years and maping higher torque in higher gears. So, in theory, they could map around crazy high torque numbers by limiting output in certain ratios.

It would be realy great if they would let the customer map thier own torque and HP curves according to each persons needs, or at least let you choose from a few?
