    Exclamation Barry Grant Mighty Demon 850cfm Carbs.

    I have 2 Barry Grant Mighty Demon 850cfm carbs.
    Annular discharge.
    P/N 5563020GC

    This is the perfect replacement carburetor for old muscle cars, street rods, performance applications and high output crate engines. Designed for engines with cam profiles up to 260 degrees duration at 0.050", large cylinder heads, large intake manifolds and higher compression.

    MIGHTY DEMON FEATURES:

    • Billet Metering Blocks
    • Patented Concentric Venturi
    • No choke horn
    • Replaceable Air Bleeds
    • Replaceable Idle feed restrictors
    • Mechanical Secondaries
    • Patented Large View Sight windows
    • Dual inlets
    • Metering blocks with tuneable jets
    (Primary and Secondary circuits)
    • 4 Corner idle adjustability
    • Built-in Power Valve blow out protection
    • Vacuum ports — 2 constant, 1 ported
    • Most common tuning parts interchange from
    other manufacturers (Jets, Power Valves, Squirters, etc.)

    Application:Well-prepared 480 - 540 cid engines

    Carbs are in good shape. I have 1 original box and instructions. I would like to sell them as a pair but I will separate. Any questions please ask. Price is $350.00 +$20.00 shipping each. Thanks for looking.

    Dam that is a sweet deal for them, I wish I would have known that before I sent my Holleys in for a rebuild at the tune of $828.16

    Are those two compatible for a blower motor? 468 Ci with an 8-71. Would they need much extra work? If so what? Please Let me know. thanks

    I bought them for my blower motor. I was going to powder coat/chrome them till I figured out how much $$ it would cost. I just bought some from Barry Grant that come powder coated from the factory.

    I personally don't think they would need any work besides a jet and power valve change to make the the same. Other than that bolt them on and do some spark plug checks.

    I run a pair of similar carbs on my 540 ci with a 14-71. They are a 850 cfm carb and I run a 85 primary jet and a 88 secondary jet with a 10.5 power valve.

    Hope that helps. Thanks.
