Irrespective of what carburetor you choose, do make sure the secondaries are vacuum actuated. That way, the vacuum signal will remain consistent for good metering. A mechanical secondary setup can see a significant drop vacuum signal, and the A/F ratio is erratic when this happens.

You can go as small as a Holley 390 4bbl with good results. The teapot was rated at 370 CFM, if I recall correctly, so the 390 is the closest flow match. If you go with side-hung float bowls, it will look very much like the OEM 2bbl carbs used by Ford in '59. I've run 390's on engines as small as the 2.3 liter Pinto motor, and as large as the 327 AMC V-8 with good results. You will need a different air cleaner and distributor - but it looks like you're on that.

You might need to change your air cleaner too. My stock oil bath air cleaner did not fit on my Autolite 4100. I luckily found a nicely refinished 58 / 59 Edsel air cleaner that was a perfect fit for $65. All I have to do is paint it the correct silver and it will look like it almost belongs there.

The summit Ford style carb I have used along with Mummert and Ted and all have had great results out of the box, the edelbrocks just don't look right on a ford IMHO.

If you're still running the stock dizzy, don't forget to budget a 57 or later one. The dual advances won't work with a new carb. Plenty of info on that here.


Thanks Mike for the reply. I have ordered a Cardone Industries 30-2808 Remanufactured Distributor to go with the manifold and carburetor change.

Are you trying to get a few more ponies out of the mill, or are you just looking for a fresh carb?  If it's the latter, a 350 CFM 2 bbl Holley works just fine.  

Thank you for your reply. I should have added more information in my post. I have a 56 Ford Fairlane with a 292 stock engine with a 4 barrel and teapot carb. I am changing the manifold to be able to upgrade the carburetor and get rid of the teapot. I have been reading a lot of posts about which carb is best and have gotten many different opinions about the size of carb I should use. I don't plan to hop up the motor, just get a reliable carburetor that doesn't break my small bank account. Thanks again

I checked with Lokar and thier AOD TV Cable adapts to holley and edelbrock. The equalizer arm has two holes in it, one for holley and the other for edelbrock. In my case, they said thier cable kit would bolt right up to any edelbrock thunder series carb.
