1bbl Holley carburetor to 4bbl Holley
I have a 1966 Dodge Dart GT with the 225 slat 6. I want to go from a 1bbl Holley carburetor to a 4bbl Holley carburetor other than the intake manifold and carburetor what else do I need to do so that the engine runs good? Example: Do I need to advance timing, adjust fuel pedal, or will this be a swap and go. Thank you for any responses. Just to avoid confusion the intake manifold I want to go with is a offenhouser 4bbl. Summit website suggests a 390 Holley.

Welcome.
That much carb increase should have a camshaft upgrade. |

More compression, head work with new valves, springs etc. port work , performance cam and dont forget a set of headers and new exhaust. That new carb just got expensive but if you don't the rest you don't need the carb.

After much consideration I think I'm going to get a 2bbl intake and carburetor. I know that will be a lot less work.

Chrysler offered a two barrel carb in the seventies I think it was called the super six. But stock parts are our there for this upgrade.

Why not get the 4 barrel and 2 barrel adapter so your ready when you want to rebuild and really hot rod it?
