    Can you post some photos please, of the choke airhorn with the stamped numbers, and of the whole carb please? Sure it's 4553 and not 4653? Gary

    No, it's a list 4553 under the list number is 1213. It's a DP carb. On the main body it has 6R3738B.

    Strange it doesn't appear in the Holley list, but neither does a 4555:

    Yeah, that's a vacuum secondary carb. Mine is not. I can't do pics on hear at this time, but it has a strange ramp linkage to open the secondaries. Throttle blade size is 1 3/4".

    1 3/4" would have to make it 850 cfm. Early double pumper linkage. Gary
