You've lost me somewhere. All 3 engines are virtually the same displacement. The Cummins has larger cylinders but fewer, so in theory it should wash, right?
They are close. The short stroke 6.6L Duramax is a 403ci, the 6.7L Powerstroke is a 406ci, and the 6.7L Cummins is a 408ci. It is not about number of cylinders, but actual displacement of all the cylinders together.
