FYI for you guys/gals wanting to upgrade:

I thought egr is no longer on 02 and up? Is it still on the 6.0l?

Good link though.

 

Interesting. The 03s have the electronic throttle body setup and no EGR. This one has the cable throttle and EGR, but has a GM sticker saying 2003. I wonder if its a service replacement motor.

Also, look at the coil packs and plug wires. I haven't seen a factory GM installed motor with those coils, wires, and mounts. Anyone else?

 

2 out of the 3 truck motors i have sitting here came with the round coils but not those wires.

after looking again i am going to say those coil brackets are diferent then the ones i had. maybe from a car, hmm.

i would probably pass on this one, too many questions and it has never been ran, with the odd stuff on the out side you have to wonder if it was pieced together on the inside.

 

Yes my Dad has those coils and brackets on his 2000 5.3. There are two different coil types. Round or the more common square ones. The wires, well I have never seen them before.

 

those coils are mounted higher on the valve cover than the set up's i have seen, not 100% sure since i sold all of those parts. i think the whole set up is diferent

 

Dont know about the wires. But I have those coils on my truck.

 

No fuel injectors or fuel rails?? Mabey its a mock up. Hope it runs.

 

that guy was an ***
I emailed him and he wouldn't ship it too me
oh well there goes having a spare motor
If anyone wins it from here I'll take the tranny off your hands

Heres a quote from my cousin who works at GMC "but they have a knocking problem that GM will not recognize"

So its not worth the upgrade to get 30 more horsepower.
