pls help with classification math

I use a 4.30 gear in my stocker/ss car. Also a 2.75 low gear in the trans helps immensely to get the car off the line but with the 4.30 rear it keeps the trap rpm around 6000 to 6200 rpm. I believe that Jasons old car is now owned by Alf Wiebe and I heard that that thing has been in the low 10.30s if im not mistaken. In SS you have to use the cast iron heads for the year that you claim, small valve if you use the 330 hp motor or you can use the stage one size valves but the HP rating is higher and it will put you up 2 classes at approx. the same weight. Talk to you later.
