The 2.7 does have higher HP per liter because it like gasoline engines can turn more RPMs but that HP is what we are talking about.

Again some misinformation; Cummins uses CGI blocks for the past 3 years.
And torque per liter is not the key measurement here - total torque and the torque curve is.
There is a reason the eco boost is not in the Ford heavy duty trucks; actually lots of reasons. Maybe someday Ford will figure out how to make an Eco boost work in their heavy duty trucks - but it's pretty telling that they've been making eco boost engines for over a decade and still don't. And the direction they are going means it will be far more likely to see an electric engine than eco boost.
Not sure why you keep beating the drum about an engine that doesn't even belong on a Montana forum discussion.
