I don't see a dealer helping you out. Nothing against dealers but to retro fit an engine and trans that's just what they don't do.
If you are going to get a 5.3/4L60E out of the salvage yard make sure you get the ECM so then you shouldn't need to reflash it.
Times two on take it to a tuner to see what you have. Then decide.
