A DP is the last carb you need on the street. It'll suck fuel like no tomorrow. Every time the pedal moves they shoot fuel on both sides. You should be able to tune a single pump carb to perform perfectly on that kind of engine. The second pump shooter is best saved for the bracket guys.
Dude! You're so right there! A well tuned 3310 can work well at what I call "Trying to straddle the fence" & is easier to tune tire spin in & out. Do some gears & put that car on a manageable diet
