Here are some cheap easy options....
4-Link - Move the top bar up a hole.... It will make it harder to pick the front and then will spin easier...
Go to a smaller tire. A 29x10.5 would be fine for you.... It will gear you down a little more and will be plenty to get some hook and wheel speed. Guys are going 7.20's on those things!
Launch harder... don't know where your converter is setup, but if you come out of the hole hotter it will carry that rpm longer.
