Desoto Street Stock Gear Final?

What final gear and tires do the street stocks at desoto run? I usually turn about 7000-7200 RPMs here at Citrus. Any help is appreciated!

I believe Most run 620. Maybe 600.

Thank you!

In the day we ran a 575 in a streat stock and 620 in the Lm. some teams JC ran a 648.
Sportsman ran a 600
