3.90 rear end

I have a random question. Do you have any idea how many rpm's a car with 28" tires and a 3.90 rear end will run at 60mph?

Thats kind of what i was thinking. I was just hopping to stay under 3000. She's definetely going to be a gas guzzler!

Is that with 3.90 gears?

Is there a real big difference between 3.50 and 3.90?

Thank you DennyW for all the information.

Hey guys I have a 3300 lb car, with 600 hp and 28" tires, and 3.90 gears. What can I expect to run in the 1/4 mile and at what speed and rpm.
