Mad Scientist Testing Carter AVS 4966S (short video)

So Carter Lied? Frankly Oliver, you don't know what you are talking about. I have a couple of Carter catalogs from the 1970s & they list replacement AVS carbs, models 6433 to 6437, for Chry engines. They have the same dimensions as production AVS carbs & are listed in the catalog as flowing 630 cfm.
Quite believable, as the unobstructed secs will flow a lot of air.
