Carb Recommendations needed for my 340

Hey all,
I'm looking to get my car on the road ASAP and I figure now is a good time to get a new/rebuilt carb. The one I bought a year ago showed up with fuel in it, and it's been a year of sitting in a dusty garage, so I'm sure it needs a rebuild. The one I have is a Holley 3310 750CFM with vacuum secondaries and no choke (assembly was removed). I'm told it started in the cold and ran well, but I'm hesitant to run no choke in New England.

The drivetrain is a 340 with 9.5-10:1 compression, iron J-heads, unknown cam (told it was decently aggressive, but fine on the street), single plane holley strip dominator intake, dougs headers, backed by a non-OD A833 4speed and a final gear of 3.55:1 in the 8-1/4" rear.

Does anybody have any recommendations on a carb for this setup? I will be mainly driving it on the street, maybe some track time, mostly cruising and lighting 'em up at traffic lights. I'm told a 650CFm double pumper will work, but I'm not sure if I have enough rear gear for a DP. Also told a 750CFM with vacuum secondaries and no choke works well (which I have), but again, I'm hesitant to not run a choke.

Thanks all.
