    Default List 4781-2 Holley 850 DP carb -- sell or trade

    Changing the build slightly again, got a different carb, so I'm selling my 850 Holley with new Proform base. Bought the carb about 4 months ago, last run bout 6 months ago adn the guy who was borrowing it pulled the jets out when he returned it to the p.o. (EDIT, read post 3...) . I have not mounted it or run it, but it is clean and appears to be iin good condition. Will need jets and bowl gaskets, but comes with fuel lines as pictured -- Asking $200 plus shipping or trade for BBC Victor R or similar tall rectangle port Dominator pattern intake..

    Went out tonight and popped the bowls off the carb this evening adn SURPRISE: It's fully loaded, just needed bowl gaskets, so I put in some that I had hanging around.

    Here's the breakdown on how it's set up.

    Primary side:
    Metering block # 12319 (only number I could find on it)
    Jets: 79/79
    Power Valve: 8.5
    Accell Squirter: 31

    Secondary side:
    Metering block: 47792 (has 8542/8543 one on each side of the block also)
    Jets: 84/84
    Power Valve: plugged with Holley plug
    Accell squirter: 31

    Insides are very clean, has brass floats, but does NOT have jet extensions or whistles. Ready to bolt on and start tuning.

    Still $200 OBRO, plus shipping
