One thing a lot of people forget is that most gas burners make their power at 4500+ rpm. Most people don't run them at 4500 even when they're pulling hard... thus they lose the entire top end of their power band. That 180 hp 'rated' engine may only make 140 hp in the band it's actively used. By comparison, the old CDC Cummins will make power at 2200 all day long; right where most people run them. Since it has a lot more torque and makes power in a usable range it gives the impression of having a lot more power. I see the same thing with our old fire trucks. One has a DT466-180 and the other is a 427. The 427 actually has more power (somewhat) but is generally doggier on the road because most guys don't understand that to get the 427 to MOVE you hold it north of 3500 ALL of the time. If you do that it will far run away from the DT.
