Does anyone have any experience with an electric choke kit for the old coil in manifold style Quadrajets? What kit did you use? How dependable is it? Information, etc?
Also, don't bother telling me to dump my Quadrajets and get a real carb! In my book, nothing runs like a Qjet on an SBC!

Thanks and best wishes,

Les

I put Q-jet's on everything of mine. I use the later model with the round choke on the side.If it doesn't have electric on it it is easy to change the coil to an elec. heated one. These carbs are a dime dozen at the swap meets.

Not sure about the "in manifold type" but the round ones on the side of the late model type work great. Just power them up and go. Never had a problem yet with one. Most of the time you can swap the whole choke system over to the older type carbs.

Why mess with something that works? The manifold-heated choke is fully mechanical. Just bolt in a new coil assembly and set the linkage right. The only function of the electricity is to heat the coil and make the choke release, so with the choke coil in the heat riser passage in the manifold there's no reason for electric heat. If you're going with an aftermarket manifold without the choke well, just switch to a Q-Jet with the round choke housing integral with the carb, and install an electric-heated choke cover. You'll have to grind off a locating tab on the cover to make it adjustable, and install an oil pressure switch to keep it from heating and releasing the choke with the engine cold if it stalls.

You're right about the Q Jet being the best-engineered street carb available. Holleys are for race cars!

Guys,

Thanks for the replys! My problem is I have an original and fully rebuilt 704 series Qjet from a 1972 C10. It used a heated element that sat in the intake manifold and worked the choke butterflys via linkage. The electric choke that I'm talking about is an after market type that bolts to the carb and has a sensor that bolts to the intake.
This would all be simpler, but the ProComp dual plane intake that I have doesn't have a place for the original type choke coil.
If it ain't one thing, its another!

best wishes,

Les

Thats why we use the round choke models. The intakes & carbs have been so scrambled up through the years that generally they dont match.
