Well Ford's contract with International AND Dodge's contract with Cummins both expire December 31st, 2009. Dodge isn't "dropping" Cummins. They're kind of in a bind being poor and all.
I think the reason that there hasn't been any "real" talk about this is because Chrysler has officially been sold to FIAT as of June 1st of this year, so even for a new contract to be written up with Cummins, the new "parent" company has to decide. But I'm sure most of you knew that.
Personally, I love a Cummins, their designs are so well thought out and executed. And let me tell ya, if Ford continued the Superduty, with a Cummins, and contracted with Allison like Chebby has done.... I'd sell my left nut for one. That would be a dream truck, and is the dream truck of many.
Has anyone ever drove anything with a Cummins hooked to an Allison...? I have. I know a 12valve with that 6sp auto (same as a dury) are SWEET. I love the hell out of driving those suckers. If you drive one like that... they belong together. I've overhauled some Cumminss and some Allisons, they are so simple it's unreal. They're pretty cool.
Now put this in your pipe and smoke it, I think Ford should do this... Contract with Cummins, put the inline 6 in there (not the v-6 thing they were thinkin of), Make the Allison 6sp an option, AND utilize Urea injection to meet Emissions standards rather than the DPF garbage, and do it sooner than later before the EPA reeeeeeaallly starts screwing us. IF FORD READS ANY OF THIS STUFF, MAKE A NOTE OF THAT
