In have a T-5 trans already installed. 351C motor with 9” rear. Any one know off the top of their head what the size speedo drive gear tooth count I need might be? Or is that too vauge of a question?
 
There are several speedometer gear calculators available online just google "speedometer gear calculator". You'll need to know what gear ratio you're running in your differential. To be really precise you'll need to know your rear tire diameter, also.
