    I was just reading the other post about a th400 and the guy mentioned about not having his kickdown cable hooked up. I didn't want to hijack his post so here is me question. Do th400's have a kickdown cable? I have checked on mine but I only have a vacum line.

    Also does anyone know what vacuum port on a Eldebrock intake this vacuum line goes to? I also need to figure out which vacuum port my distributor goes to.

    Thanks alot

    TH400's don't use a cable. They use an electrical switch, usually positioned near the carb linkeage or under the gas pedal. /forums/images/graemlins/thumb.gif

    Nope. Th400s use a detent selenoid operated by a wire.
    A Th350 or Th700r4 uses a cable. /forums/images/graemlins/deal.gif

    Manifold (constant) vacuum is what you hook up to the modulator.

    Most of the time the Q-jet port for vacuum advance is on the drivers side middle of the carb, and is "timed", meaning no vacuum at idle. The fitting size *should* correspond with the vacuum cannister fitting on the distributor, but may not.
