4bbl! :supz:

In all seriousness, get a run of the mill 2bbl, or step up to 4, that one looks like a gimmick. 4bbl spreadbore carbs are the best of both worlds.


Go to the junkyard and pull one and rebuild it. Spend your time learning to jet and tune.

How do you have a 1-barrel on a 318? I thought the only engines that would come with a single barrel were industrial engines.

Well anyway, providing you have an intake in place that will accept a 2bbl, your choices are in order of most common:

1. Carter BBD. Factory carb for a lot of years. The early ones are more simple, but they can all wear out the throttle shaft. Has a brass float which is a good thing.

2. Holley 2280. Started out as a replacement for the BBD, then Chrysler used them as factory equipment when Carter begin getting out of the carb business. They have a nitrophyl float and I've seen them have problems with the float getting hung on the sidewall of the carb.

3. Rochester 2GV. Yes, Mopar did use these for 1 year(1971)so they aren't common, and the other versions of the 2G don't fit. Nice, durable, easy to rebuild carb.

4. Assorted Strombergs, non-oem Holley carbs, Webers, etc. You are on your own with these.
