Stepping up to a DPer?

I've been talking to several carb builders, along with BG/AED & others, most said the 650dp, BG said the 750 Annular speed demon VS., AED said 750dp (dog-leg), he wouldn't run anything VS for performance orientated, I had 2 say the 3310 would foot the bill fine (one of them was Jesse from Biggs), especially sence i already have it, changing carbs at this point might not yeild much gain but cost a few bucks, i guess i'm right there with the 750 cfm range (no need going bigger), going to a DPer in a 750 might hurt 60ft. times with my gear/converter but run a bit stronger up top, going smaller might help the 60ft. times, but loss up top. So i ordered a few little things for the 3310 from a buddy of mine, rear MB, quik change top/springs, a few air bleeds.
