Ben if you run 1st gear you want 2.56 or 2.73. 2nd gear you want 3.73 or 4.10. There is also a 3.90 that is supposed to be availible if you can find it. To get 6500 you will need to run the 273 or 410

There is no track tire but a 7" tread width limitation. I would suggest the copper cobra 215/70-15 and 225/70-15 or one of it's many clones(futura, national, mastercraft and others)

If you run 78 series tires you may have to run 308 or 433 gears to get the rpm you want.

I"ll stick with the "Copper" for the first night and go for "Car beautiful". Imagine how they'll look under the lights all shined up!!

Come race time, then the Coopers definitely have the edge for traction and cornering, I'm sure.

Thanks for the help, Bill.  Your ratio advice was well taken.
