Mad Scientist Testing Carter AVS 4966S (short video)

No secondary boosters in a factory AVS.
That's true, but it does have the spray bar in the way. The edelbrock booster is the same size as the bore diameter too. There's no way that carter flowed 625cfm with the venturi sizes. It was simply carter's odd way of flowing 4bbl. Maybe someone could flow a factory avs and a edelbrock 500avs.
