Also, I don't believe the engines are 'left overs' from Wixom. There are differences between the Z/28 LS7 and the one in the Z06, namely the A/C being optional. Even though its a slight change, I can't see them running around pulling apart the front end of the engine to remove A/C and swap in a dummy pulley every time a Z/28 gets ordered.
I haven't seen the LS7 line in Wixom, but there is generally an engine dress line in most vehicle assembly plants where the FAD is installed and the engine is mated to the appropriate transmission.
Just watched an LS9 build video and they racked the finished engine without the front accessories intalled.
