I purchased my Vette used and think the car has stock 3.42 rear gears set on
my M6 car. On the hwy running at 120km/75mph in 5th gear I am at 2400rpm
and in 6th gear at 120km/75mph the car is reving at 1600rpm.

Does anyone know what the rpm for 5th and 5th would be with a 3.73, 3.90 or 4.10 gear set?

I was interested in what the rpm increase on each set would be (200,300?)
and what rpm would be good for hwy cruising?

RPM also depends on tire size. do a search(internet) for rpm calculators and you should come up with some thing you can use.
