    OK, need help with a Holley carb list 4553 1213. I can't find on any list. So what size is it and what's it off?

    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

    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
