Definitely not right for a stock 3.42 M6 car. Maybe gears/rear was changed and PCM wasn't reprogramed? Visit www.f-body.org/gears/ and plug in different ratios. Plugging in 2.73 is 67 MPH - I'd pull the cover and see what's in there.

Put in the gears and tells the rpms
6th gear 1200 rpm 67 mph
6th gear 1300 rpm 73 mph with 2.73s sounds like they swapped the rear-end.
