That's true in a general sense, but I don't think that's the primary reason the 70 series has only 430 Nm. People are considering the 750 Nm in the new Cummins 5.0 as "conservative." In fact, they are using that Cummins engine for large school busses and class A motorhomes. A 70 series is a gokart in comparison. I don't think the 4.5 is an amazing engine, the 200 series has two turbochargers and still has only 650 Nm.
