without knowing cam specs, compression, intake, etc., what car is being used in, what trans and gearing or what you will be using it for I'd be ballparking this.
I've run a 750 vac. secondary Holley on my 72 Chevelle (vs. a double pumper for the weight of the car and the times I was turning at that point, mid 13s), and my Nova had a 650 Holley double pumper that got it from high 12s all the way to mid 11s without a bunch of mods. Currently using a 750 Holley HP double pumper, and it was a tenth faster out-of-the-box over my 650, but without a choke it might be considered not as street friendly to some.
End result - more information is needed to make a clear choice.

I have a Holley 700 double pump in stock for a great price, shown above. The 700 is a great all around carb for many applications. Bob

With a 350ci a Holley 750 4150 series is what I ran for 2 years on my DD and it has great performance I ran mid 12s all day on motor and 11.26 with a 150shot not bad for a vortec motor. There is a formula that help to come up with the cfm but its just a guide.
