We run a 5.67 on an IMCA stock car, but anything from 5.67 to 6.50. Depends on tire roll out.

My 406 turned 5800 at the turn, that's with 88/89" rollout tires with a 6.125 final drive. (Muncie 3 speed, 2nd gear 1.75 x 3.50 rear gear)
I bought a set of 6.33 to put in this year, I would like to turn it 6200/6400 this year.

I haven't tried different size tire's, but I thought 1" of rollout is close to equaling 100 rpm's.

6.20 to 6.33 final drive ratio depending on what rpm you want to turn.
