    Default Identifying Old Holley 2 BBL

    Hey, I'm new to the forum and have many questions about a carb i came across for free. Its a Holley 2 bbl, I was told it came off of a late 60's Plymouth Fury w/ auto tranny (if that helps). I have looked everywhere for info on this thing and even called holley, and all i was told was that it was absolete and they then tried to sell me a new unit. All the info I have on it is what it supposedly came out of and the numbers stamped on the front of the bowl. It reads:

    R 7027 A
    3830527
    0575

    My main concern is simply knowing what it is. I would also like to find out the flow rate and eventually find a rebuild kit for it. Any info will be greatly appreciated. Thanks and have a good one!

    Google "Holley R7027A" for some information.
    It's listed in this Tomco kit interchange guide:

    I appreciate the guide, but still can't find anything on a rebuild kit. Just to be clear, "R7027A" is the list number, right?
    If so, they must have been right about it being obsolete, because there is nothing on the web I have found about it so far.
    Again, thanks for the interchange guide.

    Do you mean you can't locate the rebuild kit?
    The interchange guide I posted, indicates your rebuild kit is a Tomco 5211E.
    It also references your float, choke pull-off and choke thermostat part numbers.

    Just to be clear, "R7027A" is the list number, right?
    Yes, that's the list number, as evidenced here: http://www.holley.com/data/TechServi...%20Listing.pdf

    Yes, your carburetor is most definitely obsolete, however, parts may still be available for it.
    May God's grace bless you in the Lord Jesus Christ.
