Run without it... Seriously how many days when it's cold out are you gonna be taking the car out?

if "factory correct appearance" does not matter, run it like it is.
we milled the horn off my 650 on my boat and my thoughts were that if it was cold enough to need a choke to start it, it is way too cold to be running it anyhow.

Here's a four barrel, two barrel would be similar...

choke horm give the choke butterfly something to seal up against I run a cold intake with the heat crossovers blocked off and with the choke flapper zipped tied open foot choke it with the gas pedal and let it rip and you got it right Day2 is it  m
In this case I would just remove the choke flap assembly , all it's doing is messing up the air flow

Just a cleaner path for the air to get into the carb .

And with an air cleaner,it probably wouldn't make any difference.

I thought venturi diameter and size of components restrictions inside the venturi such as boosters,thickness of throttle plates,shafts etc determined how many cfm's a carb would flow,removing the air horn would change none of the above.
It unshrouds the openning allowing for increased airflow to the parts you've described.
1970 Plymouth 'Cuda #'s 440-6(block in storage)currently 493" 6 pack, Shaker, 5 speed Passon, 4.10's
1968 Plymouth Barracuda Convertible 408 Magnum EFI with 4 speed automatic overdrive, 3800 stall lock-up converter and 4.30's (closest thing to an automatic 5 speed going)

It reportedly increases the air flow through the carb by 50+ CFM.
MAYBE more like 10-15 CFM,...the turbulence that carb is going to see across the air bleeds is going to be more of a nusiance esp at part throttle to WOT,...IMHO for street use, replace either the body, or get another carb,...OR modify a K&N stub stack for a Holley 2300 2 bbl(pn#85-0210) to fit your 2300 series 6 pack center, the stub stack is plastic, easy to mod,...it will help direct the airflow properly thru the now missing airhorn, the airhorn does alot more than just hold the choke plate, it basically helps control the transitional changes the carb will go thru as you alternate the throttle position during driving,...the secondary system (end carbs) are a completely different "animal", and don't require venturi/air bleed modulation like the primary (center) carb requires for smooth street driveability
