As far as will high rpm on the highway hurt it? Eventually, yes: there's a reason why new vehicles with overdrive are hitting 300,000 miles and the old girls barely made 100,000.
No offense, but considerably more involved than just final drive ratio....
 The gear ratio helps but is probably one of the least important factors. Harder bores, moly rings, oil technology, and fuel injection have helped to make big strides.
Also theres lots of 4 banger cars that turn 3000-3500 @ 70 in overdrive.
