Diesel Engine design, bore vs stroke

I'm curious what you guys think. Most diesels have much longer strokes than they do bores. They are under square. I heard this has to do with that with the slow flame front of diesel it can be used to maximize torque.

Now there is one diesel i can think of that isn't this way. The duramax diesel. It seems so counter intuitive but it does make it a rev happy engine. Very un diesel like. I know i love having low end torque driving around at 1100 rpm, torque converter locked in over drive, around town. I don't even slow down on hills with no additional throttle.

This isn't a brand war here just general thoughts on these do different design philosophy.

back in the day with much lower injection pressure, which resulted in larger fuel droplet size flame front was more of an issue. nowadays with high pressure injection and more fine tuning as far as timing and such flame front moves more quickly i suspect
