    Default Fairmont 302 with VV Carb

    I have an intake manifold I removed from a 79 Fairmont with a 302 and a casting number of D9DE-DB using a VV carb.
    I know they put them on a lot of other Ford cars and trucks of that era.
    I'm not sure if this is an OEM setup for a 79 Fairmont or not.

    Thanks, Kelly

    The feedback VV2700 and then the reverse call name VV7200 from 1980 onwards was a California thing on the 78's and 79's, including the Monarch, Granada and the baby Lincoln, the Versailles.

    JA Cook had one on his 78 Fairmont.

    They have


    1. a feedback control with kerb idle adjustment via DC stepper motor which has a TPS on some versions, tied in with a Duraspark I , II, or III, and EECII, or III control system on some.

    2. and are essentially a cross mix of Carter jets and metering rods actuated by a variation on the SU carb driven Venturi, but with a special twist...its longitudinal and down draft. The green coated parts with a Nitrophyl shutter makes this such a strange beast, especially how the shutter and dashpot operate.


    Ford made this carb in non feedback type as a 2700 series 2-bbl, and also a 1 bbl carb in Europe. It lasted a long time. IIRC, 1977 was its first year, but 1300, 1600 and 2000 cc fours still had it into the 90's in European Transits and Escort Vans, and , In the USA, P71 cop cars had it, on up to 1991 on special order. Ford did a very good range of 250 page manuals on the 2700 and 7200 variants, with yearly revisions. The TPS, EECII, or MCU feedback control varied yearly as well. Ford spent a bunch in this, their last ever 100% Ford carb ever.

    US and North American Public sales were from 1977 to 1985, its last official year, but again, the police used it later, and that's because if it wasn't screwed around with, it worked really well. FoMoCo found proper training and keeping the dead beat hands outa its way was the best option, so the CHIPS "Harlan Arliss"-types made them work fine.

    Its a "bat sheet" crazy design to look at, but as long as the machined surfaces and stepper motor sensors are kept clean and properly adjusted, only an extreme cold weather event can make them dicey.


    This is the later 1979 version

    Only thing you really need to dial in a 2700VV is a good gauge that can accurately read the low-level
    control vacuum. Your standard-issue manifold vacuum gauge is not good enough.
