Hi, I have a 2000 GT ( 5 speed )and am thinking about putting new gears in my stang. Is there a calculator or anything that can tell me what my RPM will be at 70 and 80 MPH? with both 3:73 and 4:10 gears. Im trying to determine which gear makes the most sense, as I spend a lot of time on the highway. Thanks for any assistance!
