Go 64 pitch. I'm using a 88 spur with the 19 tooth pulleys and the 38 tooth diff gears for a 2.0 internal ratio. I have run from a 3.7 FDR to a 4.25 FDR and never came close to maxing out the adjustment of the vertical motor mount. The 88 spur also gives you a nice selection of pinions that most shops stock. I usually use a 42 to 47 pinion.
