you can go to www.gearchart.com
and print out a gear chart for your specific car .. youll need to input spur , pinion and final of your cars gear ratio.. When reading the chart spur sizes are on the top pinion sizes on the left of the chart pick one and go across youll have your FDR for the motor your running , as a starting point.. hope this helps...
