Default 64 pitch gearing

I have an FK05 and will be using either a 112 or 114 spur.

I'm running stock and 19 turn on asphalt with take Off CS 27's and need pinion size advice.

The motor's I'm using are...

stock...Trinity CO27 (blue can)

Mod...Reedy Quad 19T Spec

6.0 Final Drive Ratio. The formula to figure it out is (Spur/Pinion)*Car's internal ratio. I'm not sure what the internal ratio is on that car.
