Please don't quote me on this one Ross, I drive a Mini stock, but a friend works on a thunder and I think he said something about the final drive having to be around a 6.13 or 6.50. I know a big difference! ??? I'm not 100% sure.  When do you need to know by?  I'll try and find out for you!

But I will say this, in my Mini-stock(and not a top one) I am hitting about 80mph at the end of the straights.  Might help you out!

we run a 6.80 final, and turn 6400 at the end of the straight, if you run second with a three speed you can run 4.56 or 3.73 with a glide

You've been up to Capital City Speedway?

2.73 x 2.52 1st gear gets me a 6.9, so that should work... If you are talking Capital City..

Bake, yeah if you don't see the answer on here, I would really appreciate if you could find out for me. 6.13 to 6.50 is a big diff, especially if I am thinking of running 6.9... 6.13 would be a 2.44 rear in 1st, with the th350.
