I have a 96 7.3 Powerstroke so take it for what it's worth. I hate Dodge. Rented 2 brand new ones(gas) and the truck was garbage. But you are talking about a Cummins. As a whole, though not every year, best diesel on the market. The way I look at it is it's a great engine wrappred in a peice of s***. It's still a Cummins. I sure wish I could by a Ford or Chevy with a Cummins in it, if that tells you anything. Good luck to you.
P.S. this is not to start a Ford vs. Chevy vs. Dodge thread. JMHO.

See how the same power gets distributed across six rods instead of 8, look at the thickness of the Cummins rod to the old model Ford and GM diesels. 
This is so out dated......Chevy 6.2l.

P.S. Size of the rod doesn't equate to power. Length of the rod and diameter of the piston do.......at least when boost isn't involved.

You have a 13 year old Ford truck and a Dodge truck is a piece of junk? I've had (as many other Dodge truck owners have) Fords and enjoyed them for the most part. I have a Dodge now, don't know what I'll have next time. Which ever one I believe will fit my needs at the time. But the Fords I've owned failed to teach me that they are in some way superior to today's Dodge. I'm quite sure had one of those Fords been a 7.3 powered 1996, it also would be incapable of teaching me this lesson. Perhaps you should open those eyes a bit. Never know what you might learn.

Please stay on topic. I never said my truck wasn't old or a piece of junk, though it is a good truck for it's age or it wouldn't still be running . Everyone I know except one person has had tons of problems with their Dodge's. And then I stated my experiences. Thats it. Why would I rant a rave about a truck in which I hear so many bad things about from friends and then bad experiences myself. I am sure your truck is great. I simply responded to his question based in my expeirences in 2 brand new Dodges and then blew all kinds of smoke towards the Cummins. I in no way tried to make mine surperior hence the reason why I said "take it for what its worth." Try keeping your emotions out of your posting.

The picture of those connecting rods has nothing to do about the power of the engines. Look at how much beefier the Cummins rod is. What does that tell you?
The Cummins also has 25-30% fewer parts than either Ford or GMs diesel.
I'll take fewer,more HD parts any day.

I'm a Cummins owner, and very pleased with the powerplant, and I've seen this rod/piston comparison photo over the last couple years.
I will say that if you have 6 cylinders instead of 8 to make similar displacement and power, you would naturally have to have heavier rods and a larger bore diameter, and most likely longer piston stroke too.
The need to have rods on the 8 cylinder that are as beefy as the 6 cylinder seems like it might be overkill, as you are distributing out the power amongst 8 cylinders instead of 6.
Maybe we should look at the rods/pistons of a 300 CID Ford I-6, and compare them to a 302 CID Ford V8 rod/pistons. Would the I-6 pistons be larger in diameter or have a larger bore size, or would the I-6 rely on just a longer stroke to make up the displacement?
I think if we are considering similar compression ratios, the ford 300 CID I-6 might have beefier rods.
Think about it? You've got 6 pistons and cylinders making the same power as 8 cylinders and pistons, and they all have similar compression ratios, but the 8 cylinder is able to distribute-out it's power production amongst more cylinders.
Seems like rods as heavy as the Cummins 6, wouldn't be necessary.
I'm sure if you compare the powerstroke and duramax rods to an equivalent displacement gasser V8 the powerstroke and duramax rods will be appreciably beefier.
As far as medium duty and a lower duty diesel goes........I'm not an expert in that area. I've heard from many that their is a duty rating to these diesels and Cummins is higher rated, but I haven't the foggiest notion of where those ratings came from.....i.e. What agency rated one diesel medium duty and another lower than medium duty.
I will say, that an I-6 should have less moving parts, and I would assume frictionally is more efficient than an engine with additional cylinders. Of course 4 valves per cylinder will also add to the number parts versus a 2 valves per cylincer engine.
Is the Powerstroke and Duramax 4 valve per cylinder engines like the later Cummins? If so, we are looking at 32 valves versus 24 valves.
I would assume for breathing purposes, so that both types of diesels put out similar h.p. and torque numbers, that the Cummins valves would probably be larger diameter than the 8 cylinder.......That doesn't make the Cummins better, just a result of it's design in order to make the same or similar power/torque.

Good luck trying not to start a war with a post like that.
You have a very narrow minded view indeed. The place I used to work at had a fleet of primarily Ford trucks (cheapest bid, and we got what we paid for). Interior pieces falling off in your hand, dome lights that wouldn't turn off, driveshafts coming loose, airbag system problems, diesel engines giving us problems..... I could go on, but the list of problems was extensive. If I were to use your line of thinking, I would say the whole trucks were "garbage" even the engines!
But, I am an adult and I realize that not all trucks from any brand are garbage. Sure we had some bad luck with the Fords, but there are many happy Ford owners out there. And by the same token, there are many happy Dodge fans out there. You would be wise to remove your blinders and step into the real world.

So very true. The Cummins in the Dodge is a tried and true, proven medium duty industrial motor that was adaptated to fit in a pickup. Duramax and Powerstoke wer developed for their respective truck.
There are kits available to put a Cummins in a Ford or a Chevy. I am unaware of a kit to put a Powerstroke or Duramax in another manufacturer's truck. Gotta be a reason for that....

All three engines are good engines. I am partial to the Cummins. Second choice would be a newer Duramax. No way I would own a 6.0.
The Cummins 5.9L ISB engine is so widespread it's not even funny. It's used in Marine, Generators, Oil fields, Buses, Military Vehicles, Construction Equipment, and a few others. It has been in production since 1989.
Here is a updated pic of the different rods used in the big three engines. I think this was taken at a State Fair back in 05 for the 06 models.

...all true. The Cummins 5.9L is also used in a number of agricultural applications (Case tractors and loaders primarily).
