Do you have any tunes? I wouldn't use the 500 mod valve. What stall converter do you have?

Go back to the stock size .372, I think thats what it is. I would drill the #2 .076, #3 .081 and #4 .076. You can always go bigger later but that gives you a good start. Any bigger and the shifts are real firm. It doesn't have to shift hard to last. It's fun for a while but gets old quick.
