    Has anybody used one successfully? I never saw a kit for the Dauntless listed, is there an adaptor available?

    On another subject, does the Delco distributor retain the balast resistor used on the Prestolite setup, or does it depend on the coil only?

    Thanks

    It's a progressive 2V, not the same configuration as the Rochester. One barrel is a 32mm primary, and the second is a 36mm secondary. To get the mixing right, you'd have to rotate the carb 90 degrees to the usual 2V position, and maybe add a plenum between the stock manifold and the carb. Not a straightforward application.

    Ballest resistor. yes you would use a ballest resistor on the delco point style distributor.

    Ballast resistor or carburetor thread?

    Keep the threads to one topic please.

    I don't think you'd be happy with the performance of a 32/36 Weber carb on a Dauntless, it just won't flow enough to feed the 225 unless you have your foot in it all the time, and even then the top end will be weak.

    A 225 ci engine running at 4500 RPM will need about a 300 CFM carb at 80% volumetric efficiency, whereas the 32/36 carb came standard on the early Ford Capri that was only a 140 ci engine that needs 210-250 CFM at 6000 RPM.

    Thanks for the input.

    Is there any other straightforward carb replacement, or should I keep working with the Rochester?

    I'm having trouble with an off-idle flat spot that is resisting all the normal solutions.

    An off-idle flat spot is likely to be as simple as a vacuum leak. Have you tried the usual methods to rule that out yet? A can of carb cleaner, sprayed around the carb base, intake manifold gaskets and vacuum lines while the engine is idling will do the trick. If you detect any change in idle speed, you have found a leak.

    I think I'm good on vacuum leaks, but it's alway worth another look.
    Dwell angle is as close as you can ever get a Prestolite setup.

    :oops: I stand corrected, the Weber 32/36 is rated for 300 CFM, so it should flow enough to feed a Duntless V6. You would still have to work around the manifold plenum issue though, otherwise the progressive carb will only feed 3 cylinders until you open the secondary bore at WOT.
