Putting the G8 away for the winter so I picked up a 2003 Tahoe Z71 5.3 with the 3.73 rear.
She's at 140k miles, but according to the 2 inch thick bible of maintenance receipts I'm fairly sure it was well taken care of.
Anything worth looking at in the bin file for either passing performance or highway mileage?
I did some poking around and the trans tables a lot simpler than the new A6's.
