I think it's great that you do your own engine work, but just FYI, diesel engines don't have short piston strokes. I'm not sure where you ever came up with that idea.

In fact, the Cummins 6.7 is an undersquare engine just like most diesel engines.
"4.21 inches bore (106.9 mm) and 4.88 inches (124.0 mm) stroke"

Gas engines certainly don't destroy themselves if used at max torque unless they are just poorly designed. A Diesel engine will normally last longer (assuming both are maintained well) due to several factors such as the fuel being a lubricant and the much lower RPM. The torque curve is there - it can be mostly flat on a lot of the newer turbo engines but that's a function of the turbo. If you don't believe me, here is the torque curve of a BMW N54 3.0L Gas engine:

Turbos give great torque curves.
