Well, in any case this 6.1L is a sorry engine if it's meant to compete with GM's 8.1L or Ford's 6.8L.

Maybe they will pull a fast one and surprise us with an entirely different gas motor for their HD pickups. They better because this thing is starting to sound like a joke for a towing engine. I'm sure will tow ok, but no way in the same league with the other two gas engines it has to compete with.
