So 70hp/60tq and steeper gears buys you 0.73 of a second. Impressive powertrain, and I mean that. The 6.7L is strong.

Now if Ford would just update the cheap hard plastic interior by rubbermaid, and the twisty 1999 frame.

That and the fact that the Ford 6R140 also has a much shorter first and second gear that the 68RFE. The 6.7L V8 Powerstroke also has a longer rev range than the 6.7L Cummins meaning you stay in gear longer instead of shifting and wasting time in a 0-60.


I drive a 2014 Ram 2500 Cummins and even used to work at Cummins, but that the Scorpion 6.7L is a beast as well. If my only desire out of my truck was 0-60 speeds then that would have probably been my choice, but other factors that I thought Cummins/Ram did a little better is what turned me towards buying the Ram like the auto exhaust brake and better fuel mileage to name a few. Still, there is no denying that that 6.7L Scorpion is more powerful. Although my truck is tuned and is making way more power than that stock Powerstroke. I really don't think I would want my truck being any quicker than it now.


On that frame twist comment. There is a reason why the Ford bed frame has more flex than the Rams and the GM and Ram marketing team that posts those videos knows this. It has to do with the fact that the Fords frame is a C channel frame just like every Semi-truck you see flying down the road, and the Rams frame is a fully boxed frame. Fully boxed frames are more rigid than C-channel frames and hardly flex in comparison to a C-channel. Does this mean a C-channel frame is weaker than a fully boxed frame? No, not at all. The C-channel frame has thicker wall sections which is where it gets its strength, but this makes them heavier. The major benefit of a fully boxed frame is that it is lighter because it has thinner wall thickness, but gets its strength by being fully boxed to compensate. However, the major downside to a fully boxed frame is how much harder it is to up fit things like a utility beds for fleet buyers, and we all know how much Ford caters to their fleet buyers. This is why Ram 4500 and 5500 cab and chassis models have the very same C-channel bed frame that Ford uses so it can easily be upfitted. Ford uses the same frame with their cab and chassis models as the do with their pick up models while Ram uses a fully boxed frame on their pick up models and a C-channel bed frame in the cab and chassis models.

This is why you never hear Ram or GM say that the Ford frame is "weaker" in any of those videos. Because they know it isn't and the flex is just an inherent property of a C-channel frame versus a fully boxed frame. All that they are doing is good job at marketing and selling to people that don't know any better.
