Actually dodge has used cummins since the 80's..,
And yes Ford was involved with cummins during that time....late 90's into 2000's IIRC... that's why I said ironically in that post...
I always thought a super duty with that cummins would be a beast of a truck...
Yep - I knew Dodge / Cummins went back a ways. I didn't know about Ford's relationship with them, however. Of course, Mopar was less of a threat then than they are now.
As for a SD w/ 3rd party diesel - I was going to say that Ford had too much pride to put anything other than a Ford engine in their HD trucks - and then I found out just now that the earlier Powerstrokes were actually designed / built by Navistar / IH - and with that, we've come full circle in this thread!
Unfortunately, the Powerstroke engines weren't regarded as well, long-term, as the XT trucks or MRAPs that started this thread off.
The current 6.7L Powerstroke is a Ford design, though (along w/ some Austrian company). How long until an EcoBoost something or other makes its way into a SD? They can't make the truck any lighter, now that it's aluminum-bodied like the 1/2 ton is.
