I wouldn't go bigger than a 700dp, even if you do go to the sauce. Nitrous seems to like a smaller carb so the 700dp will work. I think a 650 will work fine, and Dark Knight has it right the vacuum guage is the best way to tell.
Keep the 600dp for the street, swapping a carb takes maybe 5 minutes so use a bigger badder one at the track and then switch back. That way you can ditch your choke.
