Really depends on what speedo/motor your running. I have been in the 3.1 - 3.18 inch roll outs with normal speedo. 73 spur 40-45 pinion depending on tire size.

As said above, depending on tire size! I am running a 74 spur with a 42 pinion and it flies around our track!

I may be wrong here but I believe all newer cars use 64pitch. Only thing I've found that use 48 is my TC3 for vintage. But I've been wrong before.
