My dad has a 1993 Corvette with a six speed as i said, It have stock rearend gears. I would like to know if he switched to 410 gears,what would happen to his RPM?I know it would go up, but how much? I know it depends somewhat ont the gearing and the tranny he wants to know what would rpm change is at diffrent MPH increments through every gear. And how do you know this also? I need the answer in about an hour

I've heard that the RPM's will rise around 400 in each gear at all speeds.

ttt, only 20 minutes before i call my dad,who else has done the swap,and how much did it go up?

The RPM will change by the same ratio as the gear change. Stock LT1 gear is 3.45 so the RPM at a given speed will change by 4.10/3.45 or about 20% higher. Tell your Dad to do it, he'll love it.
