6.0L and 5.3L weigh the same thing. It's the same block.

 

BTW my truck with me in it weighs 5070lbs.
ECSB 04
I have a roll pan, no spare,no jack, reomved speaker box and i guess if i lost the tailgate thats another 40ish lbs.
My truck is freaken heavy man....

 

With 1/8 tank of fuel my truck weighed 4520. That was with me in it, toneau cover on it, bed rug in it, 20" wheels, etc. My truck is a RCSB 2wd fleetside with a 5.3L. I also have manual (yes hand crank) windows, but with power locks.

I went back and weighed the truck a couple weeks later with 1/4 tank of fuel, no spare, and no jack. That weighed me in at 4500.

 

Road weight, 5350lb's, race weight 4950lbs with me in it (no spare, no tailgate, 1/4 tank of gas, tonneau off), I'm 220lbs. 2x4 rc/sb ram. I could get it down to 4600lbs or so if I started unbolting sway bars, drop the tow bar frame, remove the passenger seat, and goto some small 17" rims with 28" or shorter tires. Dodge's be a little heavier then your Chevy's.

 

My truck with no spare 1/4 tank of gas and the 15's with the ET Streets weighs in at 3880 that is a RCSB stepside. Mine is an OBS and I think they are a bit lighter.

 

sportside or fleet? Sportsides are lighter...have you weighed it on different scales and got the same results?

 

I'm fleetside... I weighed on two different scales and got within 10# of each other... I'd say its pretty accurate... that was probably only the difference in fuel from one time to the next. dunno.... maybe I have some sort of truck that Chevy forgot to put all the parts in... LOL.... anyway, Thanks Chevy!!!

 

No, the 5.3 block and the 6.0 blocks are different. But the weight isn't much different.

 

I wasn't speaking of it as a comparison for internal differances. I was just making a statement that the weight damn near dead on and woudn't make AP's truck weigh in 100's of lbs more.

 

Gotchya.
I saw this;
and wanted to make sure you knew they are not in fact the same block.
