First thing I picked up on is the fact that he's running 3k rpm at 65 mph. Should be running around 2K +/- depending on the rear end ratio. Mine runs around 1900 with the 3.92:1 rear end. So, either he's got a high ratio rear or he's running with OD off. Should be consumng gas like like it's a cold glass of iced tea on a very hot day :-)
