Yeah, the 7.3 doesn't weigh very much compared a lot of other diesels. The 5.9 Cummins weighs about 1040lbs. Hell, Cummins 3.9L 4-cyl weighs 815.
Of course, then there is the Duramax - it weighs 836, due in no small part to its aluminum cylinder heads. I wonder how well they will hold up over time? More importantly, I wonder how the head gaskets will hold up - after all, the differential expansion rate between iron and aluminum causes degradation of head gaskets in iron/aluminum combination gas engines. Unless they have a completely different head-sealing method, I would guess that head gaskets would degrade rather quickly in this application.
Anyone know for sure?

well I would of never guessed that the 6.0 out weighed the 7.3. I know this is the wrong forum but how 'bout the 6.8 and the 5.4?

just messing with him. 
but it was so random, we are talking about the weight of the engines, and then he goes and talks about how he doesnt have any problems with his truck except for a transmission sensor.
unless he has a durasmack, and was talking about that?
