Looking for advice/tips

I'd say the compression ratio is around 9.5-10:1, it still runs on 91 pump gas. The torque converter is an off the shelf 10" 3500 stall. I run the 2 step off a button.
Then a purpose built torque converter will help u a few tenths if the rest of the combo is up to the task. What does it stall at now? Flash stall? Kim
