How do I determine my gear ratio?

I'm going to use my Gran Torino as an everyday driver. I'd like it to be quick off the line but not real interested in top in speeds. I will occasionally go on the hiway to travel to car shows. 100-200 miles away. Any suggestions for gears?

what transmission you running?

C6 Automatic

You can do it the longhand way and calculate your tire size and rpm at cruise speed. Or guess at it. 3.50 is a great all around gear, 3.73 is pretty good on street depending on tire size. I wouldn't recommend going lower than that without an overdrive. Go to summit and buy an auto math handbook if you dont know the formulas.

Thank you very much.  I just ordered the book.

Do yourself a big favor and go to the apps store and download the TREMEC Toolbox, great app that doesn’t cost a penny.

Or go here:  http://www.wallaceracing.com/Calculators.htm    I use it all the time and it's free.

3.50 gear will be perfect. 3.70 will be a little better off the line. No lower unless you have overdrive.
