Another thing is the 6.7L weighs ~1450-1500lbs.

A 5.9L is ~1000lbs, I think. That's 50% more weight on the front axle (not really, but it sounds worse that way )

Does that mean a 2wd truck will be 50% worse in the snow too

I think Dodge will have to switch at some point because the diesel wars are just getting started. I'm no expert, but I would figure that the 5.9 can only be tweeked so much. If ferd actually releases this 6.4 twin turbo that everyone thinks will be the cats *** ( and how couldn't you after the wonderful 6.0 ) then Cummins will have to step it up. I personally think we will see a Cummins v8 in the future to go head to head with GM and Ford.

The structural engine may, but since the 6.7L is basically a stroked 5.9L, the truck version (even with a raised deck and a bellied-out block) should be closer to the weight of a 5.9L. It shouldn't be a "deal buster".

Didn't someone find a VIN code for the 6.7L Cummins in some Dodge literature? Given that, they must be at least considering putting it into some Dodge product.

It should be a no brainer for Dodge ... Just switch to the ISC (and the ISL for the 4500, 5500 models), a 8K front axle and add 9 inches to the nose ... thats easy ... then watch Ford and GM go insane knowing there will be no way they can win.

The 6.7L is a structural block only right now. But you're right, it is just a stroked 5.9, so I'm sure if push came to shove, something could be made to work.

But an engine with a 5.02" stroke would not be one I want hammering along ALL day at 3200 rpm, so it would still not suit some people and their "gasser like" diesels.

Reason I was thinking about that 6.7l is because of emissions. Will they be able to get the 5.9l to pass '07 emissions regs? I know that the generalization is to lower displacement to meet stricter emissions standards but maybe they've got something up their sleeve. I don't know and it doesn't really matter to me as long as it's still an I6. Please no v8's. Leave those for the 1/2 ton trucks. As for Cummins in a Ford for '06, Ford isn't that smart. Of course if they did, I still wouldn't buy one because Ford would insist that they do the ECM programming and therefore screw up a perfectly good engine. I must say it will be interesting to see the next PSD but even more interesting to see the next Cummins.

Why stoop down to head to head? The Cummins is already out of their league. Dodge does desperately need something to compete with the F450's and 550's though! I wrote dodge an email, know that won't do much but I want to see what they say.

BTW v6 and smaller v8 Cummins are currently being tested for 2007 or later for light duty(1/2 ton trucks and SUV's). Saw a pic in a magazine, granted photoshop is better than ever now but it was a legit mag that has solid spy reports...i'm looking through my collection to find it, listed liters and power output.

okay i've got this whole issue figured out...?
mercedes currently has an inline 6 6.5 liter diesel pushing 650lb-ft that they put in the lightweight 5th wheel haulers(equivalent to an F550 for towing capacity but with a near freightliner sized cab), since mercedes owns dodge and now ford owns part of cummins...are you pondering what I'm pondering?
just some thoughts. anyone know anything about the mercedes diesel? they seem to do well building their cars...

FYI-- The "Typical MOpar answer" is usually to BORE out the engine they have, not stroke it.

340 is a bored out 318 (same 3.31" stroke)

400 is a bored out 383 (same 3.38" stroke)

413, 426, and 440, ALL share the same stroke (3.75")

I'm guessing you meant that the typical Mopar solution is not to design a NEW engine, but to recycle as many part as they can from the old? *THIS* I would agree with.

The new 5.7L Hemi has a 3.92 bore (318 bore) and 3.58 stroke (360 stroke)-- anyone surprised by that??

Guess what? The rods are the same length, too-- 6.123, as they have been on all Mopar small blocks since the '57 A series 318.

I'm pondering how there is anyone left in the USA that can possibly believe this since it's posted about every day on every truck website and just as quickly smashed.

Yep, it never seems to end. In fact, one truck rag out there printed an article about GM owning Cummins. Since its publication (and I cant remember what mag), I swear I have had 4 people try to argue the point. I just nod my head and walk off.

I think they are referring to the 2.5L being a stroked 2.2L. I can't think of another example, other than some believe the 413-426-440 RB's are just stroked 350-361-383-400 B blocks, but the RB decks are 1 inch taller than the B's. Most other dimensions externally are the same.
