#1) 5.3L from a 2001 Chevy Tahoe. 185k miles pulled out running but it was eating oil and I also believe it had a blown head gasket. There are visible water marks on the front of the head that leads me to suspect that it was a blown head gasket. There is no water in the oil. It ran fine before I pulled it out and swapped to a newer 5.3L in my Tahoe. --SOLD!!!!

#2) 4.8L from a 2003 sierra rcsb. 120k miles also pulled it out running. This one lost compression on cylinder number 7. I am not sure what it was. I didn't take my time to check. I pulled it out and swapped in a 5.3L. $125 picked up for the complete long block.

Does the '01 5.3 fit into a '05 truck that has a 5.3? What are the differences, if any? I am interested in it.

Thanks

Chad

 

Only diff. I think would be the 01 has manual fans and the 01 I think is drive by wire throttle body vs. The 05 has electric fans and electrics throttle body

 

Cool, I can use my intake with fly by wire and swap out components as necessary to fit. Just as long as it bolts up I'm good.
Thanks!

hmm, you travel at all. I am in killeen may be interested in 4.8. Now if i could find some 05 up 4.8 full float rods

 

How low of compression are we talking about on the 4.8? I have a buddy who's been looking for a 4.8

 

this thing had zero compression on cylinder #7

 

Got a video clip of how it happened?

 

Hahahaha! No video!

 

4.8 still for sale!!!
