Connecting rod comparison pictures

[Motorhead]

A few years ago someone had the picture comparison of the Cummins 5. 9 rod against the Power stroke and Duramax. I can't find it. Anyone have the link? Thanks.

You can do an image search on yahoo to find the photo.

I love the cummins at much as all of you do, and i can agree from the picture the cummins parts look much bigger and heavier. and it's a cool picture. but you are comparing a strait 6 to two v8 diesel engines. the v8 parts with a overall similar displacement are going to be smaller no matter what. the engine has 2 extra cylinders, smaller bore and stroke. Not discrediting cummins, i still would rather have the inline 6 anyday. this comparison just is just misleading. just my opinion.

Oddly, the thing I find more interesting about this picture is not how much larger the Cummins parts are. It is that the Ford 6. 0 seems so much beefier than the Duramax 6. 6!! Connecting rod is way beefier, and the main bearing looks similar in size to the Cummins!! Are you sure the Duramax con rod isn't from a small block Chevy instead?

iirc, the Ford rod shown here is a lot beefier than the old 7. 3 rod.

The differences aren't as pronounced as they were when the Cummins was compared to the 7. 3 and the 6. 5 Chevy years ago. The 12V rod was also heavier than the fracture split rod used on the CR engines today.

Does anyone have that older picture? That was the one I was looking for.

Yeah... . That's the one. Thanks Ryan, I couldn't find it.
My Dentist just bought my late elder friends (Dan's) 2007 Dodge Laramie 5. 9 4x4.
He was looking at the chevys. Dans '07 only had 10,500 mi on it. My dentist loves the truck and saved himself about 16 grand AND all the new smog crap. I printed him off the first picture posted to show him that the Cummins was a whole lot beefier that the rest and showed him why it was going to last longer.
The NEAT part of this whole deal is that I still get to work on the truck.
He wants a Pacbrake prxb, possably some dyna spin free hubs and a smarty jr.

That picture is a good depiction of how low end torque is produced... . Has anybody compared the rod ratio numbers of these three engines???

I think the weight of these rods would be interesting. Suspect six Cummins rods would be considerably heavier than eight Ford or Chevy rods.
