Which carter Avs carbs were 625 cfm. I know the 340 carbs were but what about some of the 383 Avs carbs? Were any of those 625 cfm? Does anyone have a list for the Avs carbs that show part number and cfm?

I was told the 340/383 avs were the same but that's why everyone wanted the 440 one for the 340. but I could be wrong.

I have considered getting a 440 carb. Just not sure if that is the thing to do or not. Most likely my car will never have a stock small block. I am sure it will have some sort of cam even of just a .450 lift or so. Not looking to run this carb at the moment as I have a six pack right now. But just collecting for the future. Would there be any drawbacks using the 440 carb? I know the primaries area ever on the 440 carb and I would have to use a spacer with it.
