I have a 63 292 with a 2 barrel Holley carb but what type of Holley carb is it. I am trying to get a rebuild kit for it but don't see anything on the carb that says the type. Is it a 2100 or 2150 or is it something else. I am not sure if it is the stock carb or not.

Center pivot bowl makes it look like a 500 cfm carb, 350 cfm has the same appearance, might even be the same kit.  There should be numbers on the choke horn, like List-4412  and 2381.

The number on it is 4412-s what does that mean is that the number I need when getting a kit.

A google search of 4412s shows it's a 2300 carb.  Holley lists the kit part number 37-1543
