What carb??

I've got a mild 383 in my Duster, 10.0 comp, bigger valves, Eddy RPM intake, Mopar 484 cam - 727 auto and 4.10 gears... It's a weekend crusier but would like to hit the strip at some point. Like to have fun on the street though. What carb would you guys recommend? Holley Vac Sec or DP? What CFM? Is 650 enough or should I go 750?
