    Hello everybody, I am looking for some info on what kind of carb setup I should go with on my 50 Chrysler Windsor. I am in the process of making my own intake/exhaust, and would like some input on what will be the most effective setup. Will 3 singles feed 6 cylinders better or wil it be too much? How hard are they to keep tuned? Or should i go with 2 singles, or even 1 double barrel? The motor is strong, and most likely i will be getting the head shaved in the next month. ANy help would be awsome.

    In 56 plymouth had a 2bbl optioin that raised the rated HP from 125 to 132.

    I have a modified 230 with upped compression and dual stock type carbs, the puts 127 to the rear wheels at 3400 Rpm, factory was 125 at the flywheel at 3600

    .060 milled, .030 over on the pistons, stock cam and single exhaust.

    Check out member moose website for some manifold and carb ideas.

    Yeah, i have been looking at moose's manifolds. They look preety sweet. I think i will probably go with two singles. Looks good and not to hard to sync.

    There is a '49 Plymouth coupe in the Bay Area with a 265 Spitfire and it has triple deuce '94's on it with headers, a HEI and a strong cam with a lot of valve work too. The valves trick is expensive but it sure helps those engines run fast. I think the Vic Hubbard Speed Shop in Hayward could be a good starting point for information.

    I ran a single 2bbl on my Mopar 6. It was 0.30 over with Dodge crank, milled head .060, with Fenton headers. I used a single carb so the vacuum advance still worked as designed. We made an adapter to use a Holley-Weber 5200 32/36 progressive 2 barrel. I had to jet it up some but, it worked great as it really helped the torque curve, eliminated hot start problems and was very dependable. I used it in a '46 Plm sedan. With overdrive and the air conditioning on it would get 20mpg.

    That sounds like a very good package and the progressive 2-bbls are readily available.
