    I need some help identifying a holley carb I just got. The numbers on the air horn read LIST-4543-s then underneath that it says 992. It is a mechanical secondary car with what seems to be a progressive linkage. What I believe to be side hung fuel bowls the primay bowl is missing but the seconday side has jets.It has a choke horn but no flap in it. Plus I think it has down leg boosters? A friend gave me this carb. Any ideas of the year or CFM rating.

    Thanks Adam
