6.7 liters is still 6.7 liters whether you have 6 cylinders or 8 cylinders...

Powerstroke and Dmax V8s will make their power in roughly the same RPM range. Don't understand the "laid back" comment...

You're right the Powerstroke and Duramax have similar power ranges although the GM can keep making power a little longer. The power drops off quite rapidly after about 2900 rpm with Ford where as GM can keep it up till about 3200. (I'm going by memory here and might be off a bit on exact rpm but the idea is on). The difference in behavior of the two engines is huge. The Ford is tuned to loaf along with your foot to the floor towing up a hill at 1900 rpm in 4th gear....if it was to be tuned more like a Duramax it would be eager to drop into 3rd and rev to 2500 where it is making more power and would start accelerating. I tow with both a Ford and Duramax and personally like the "laid back attitude of the Ford".
