I always liked this pic...not necessarily relevant, but still kinda cool, especially for a cummins fan like myself.

HAHA!! yep

That's the other thing I always liked about the Cummins as well. It makes almost as much power(compared to the 2010-11 trucks, in the past it's made more) as the others and does it with "two less" cylinders.

Another notable mention for the Cummins driveshaft is that on the new 6.7's they asked owners with 200k+ miles on their trucks to submit their driveshafts to Cummins for an evaluation. They took a driveshaft with 250k on it, put it in the assembly line and it still passed inspection for a "NEW" driveshaft. Not to mention Cummins has 40% less moving parts in the motor as well(i.e. Longevity )

While I agree with you on the proven longevity of the Cummins, the Scorpion is a brand new engine. Who knows how it'll do over the years. I'd take the super duty over the other 2 any day.

I don't know, the Scorpion is a brand brand new motor. It's bound to have bugs(being in the Powerstroke vein) in it. Plus GM and Ford are having to meet to new 2010 Emission standards and are both having DPF issues. At least the Cummins 6.7 is just a punched out 5.9(proven design) with the Emissions crap added on to it. Not saying that Dodge hasn't had DPF issues but they've had since 07.5 to fix them and the new 2010-11 trucks seem to have finally gotten the DPF issues fixed(thanks to Dodge having Cummins involved with the new design for the DPF).

Ford makes a nice truck but they have a bad track record with the Powerstroke. Everyone I've known(with the exception of two guys) that's had a Stroker has hated them. And it ain't for performance issues, it's mechanical. I know there's good Strokers out there, I've yet to see many of them though. With the Cummins it's reversed. You don't see bad ones and when you do, it's rare and usually due to driver abuse.
