Default 6.0L and engine covers/ LQ4 LQ9 Question Pictures

Which plat forms got the full engine cover for the 6.0L? I have a 2003 2500HD and it only has the center cover, not a full center/left/right. So which got the full? Was it just the Denali 2500's or Escalades?

How can you tell externally if its an LQ4 or LQ9?

I dont think you can tell externally the difference unless you take the heads off and view the pistons.

Dont expect it to be a LQ9 just because it has full engine covers.Just did heads/cam ect. on a 02 denali with full covers,its a LQ4

Ryan do you know what the engine came out of?
Maybe you could do a cranking compression check and compare it to a known engine.

So, there is NO way to tell, with out knowing the donor vehicle.... So, what came with the LQ9?

Chevy SS trucks
Caddy Escalade

anything else?
