Both engines can easily and reliably make well over factory power levels
I hear this statement from time to time but I have to ask why did Cummins change the internals to handle the 1,000 ft/lbs. I would have expected no internal changes if this were true.
Oh save your breath, Shiner will never admit different power output has any effect on engine durability.
He'll tell you because the stock internals can handle 850hp, an ISB has identical service life from 250hp to 849hp. Stronger connecting rods are strictly for emissions...
I never said that in our debate. In fact I said that after a certain point power levels will have a significant effect on longevity. Our debate was about why there were different power levels on medium duty diesel trucks which was mainly due to cost and the application they were going in. It had nothing to do with longevity which is what you were saying was the reason for the different power levels.
