    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?

    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.
