Here are the dyno numbers:
2006 Duramax puts out 650 ft/lbs of torque.
2006 Cummins puts out 610 ft/lbs of torque.
So much for the long stroke putting out more torque.
I can hear the fan bois all ready saying that's not fair!! Your Dirty Max is a waaaaaay bigger engine!!! Fine, more facts:
2008 Duramax 6.6 L vs 2008 6.7 Cummins:
2008 Duramax 6.6 L = 650 ft/lbs of torque.
2008 Cummins 6.7 L = 650 ft/lbs of torque.
Well would you look at that? Same exact torque even though the Cummins has a waaaay longer stroke. :B
As somebody that has used a lot of torque out many engines I can see a major problem with the numbers you post; You only list peak, and don't relate it to RPM. This would matter if the engine worked at that RPM. But most useful would to compare the graph of torque output over the RPM range.
