Does anyone know what the weight difference is between the Cummins 6 cylinder and the two V8 diesels? I have a little bet here at work with two Furd and Chebby guys that insist their V8 diesels weigh more than my 6 cylinder does. I could swear I saw somewhere that the Cummins out weighs both of them.

 

Sorry, I meant to post this in the 2003-2007 section if this can be moved to that section.

 

I'm fairly certain that my engine weighs in the 1200lbs class (dressed and wet)

I don't know what the Duramax or International weigh.

 

no way the V8's weigh more. duramax weighs 837 pounds dry. didnt you know that aluminum is light?

 

Last time I weighed a 5.9 common rail I think it was like 1025 with a wooden skid.

 

Cummins is the heaviest of the three.(1100lbs). There are pics around that show the crankshaft and the huge bearings almost 35% larger than the powerjoke. The only engine that is certified to be a medium duty engine.

 

Cummins at one time had that type info on their web but it disapeared a few years back. I believe the old 12 valve was 972 lbs. The Cummins 1st gen package at assembly point was 1200+ lbs which included 2 batteries/bigger radiator/ etc. It also had the crankshaft at 147 lbs. The 3rd gen Cummins is a bit heavier.
The Cummins is a MDT specked and built engine that is used in our 2500/3500 trucks with a 350k service life. The PSD/DMAX as used in their 2500/3500 trucks are LDT specked and built with a 200k service life. The DMAX as used in the 4500 trucks have different fueling and engine componets that GM says are MDT compatible such as EB as a factory option.
The Cummins is heavy for a reason.

The Cummins (5.9) is around 1100, the Powerstroke is ~ 800 and the Duramax is just a bit lighter than the Powerstroke.

But looking under the hood, you'd swear the V-8s were much more massive than the Cummins. Looks are deceiving!

 

PSD is more than that. As I said above, the dmax is 837lbs

 

the 6.0 powerstroke is a little over 1000 pounds I think or just under.

The 7.3 was like 980 or something.

 

You guys quoting weights, what does that include? To make it meaningful we need to know what is being weighed (long block, short block, accessories, etc.).
