Carb choice on my new intake

Now that I have a new "strip dominator" intake, I need to choose a carb. I currently run a 670 "Street Avenger" on a single plane, and it works quite well. I'm hoping this will still be enough? I make peak HP (378 ) at 6800 now. 5500 to 5800 will be my RPM limit, as I don't need to see parts flying out from under the car.
