Cummins holds all the cards, they're the only reason Chrysler has a successful pickup line. Chrysler can't really push them much or Cummins could simply walk away.
What then? Mercedes is out, they dumped Chrysler for a 70% investment loss (Buy $30b, sold $7b). International is a possibility, but they'll be in a worse position than Ford. Cat is not possible, they chickened out of the on-road market because they don't have the engineering talent. Detroit doesn't have any small engines, and if their DD series is anything to go buy it would be a quality/design disaster. Build in-house, HA!

if that is true than why doesnt the people at cummins see this? the reason i believed that chrysler was holding back is because i read that cummins can put what ever hp/tq the customer wanted. so i figured chrysler was holding back due to warranty issues

^^^Na stay with Cummins! sure Ford and chevy might be a little ahead in hp and tq but, not to worry, Cummins hasn't exactly gone to bed. I've seen Cummins put out new Big rig engines and a crazy hot red 6.7 that had a different dressing then the current one. Everyone says Chrysler is lucky cause Cummins..that may be but all three trucks have engines made by someone else. Sure Ford has their'new' engine, Chevy block is made by Isuzu[dont believe marketing hype] the Duramax is Japanese[noting wrong with that] Anywho, most of these trucks get pumped with all kinds of power adders out of the dealership so i guess it's only a question of realliability:c: I only hope Cummins sticks with the I6 why? oh just cause almost every semi in the USA has one:tu:

They do! Thats why they aren't jumping head first into the horsepower game like Ford. Why would Cummins want to sacrifice more reliability when they can sit back and ride on their good reputation knowing they don't need Chrysler to be financially and publicly successful?

Which most of the cost goes back to Cummins. Cummins knows this and thats why they are slow to upgrade. They don't want to quickly toss out ECM upgrades (Ford) without through testing just so they can be #1 by a single digit in horsepower or torque.

Thats the key there. Outside, the rest of the world uses V8s and V10s in their semis. Even Volkswagen makes successful semis in europe!

It's true they make some awesome trucks in Eurpoe... they may have more pistons but, smaller rods/pistons then a I6. I mean the i6 design stands the test of time and mileage. Everyone seems to think that if it's a V8 it's automatically more then an I6. Check out FordCummins.com there's a pic there on the right of all three rods[you can see where the strenght comes from]. Then there's the simplicity of working on the I6. Don't get me wrong i'm an enthusiast and i like Ford, Chevy and of course i drive a Dodge. The test i saw of all three pulling a 10.000lbs trailer=Chevy won all the tests other then Ford pulling the trailer :c:uphill

Why is this even mentioned anymore? OF COURSE THE RODS ARE GOING TO BE STRONGER! Each rod has more force to handle because there are ONLY 6 of them as opposed to 8 to handle the SAME horsepower and torque.

If you ask me, thats a big difference in sizes, obviously. But think about it, thats just the extra force of 2 pistons spread out across all 6 pistons. It looks like the Cummins rods are built to handle that extra force AND then some!

Not really. Ford and Isuzu's engines are made to revv higher, thats how they make their power.

If that is your theory, I want neither. I'm looking for TORQUE, not as much horsepower. an engine that makes peak "power" at 2500 - 3000 is pretty much useless for getting a heavy load to start rolling.

Now something like a cummins, where the curve starts at about, 1,500 rpm. That is how you get something rolling from a standstill.
