This is another reason I wish people would just leave these cars stock. All the mopars I had that were left factory original were ultra reliable. Chrysler engineered all those parts to work together perfectly. Then someone plays mix-n-match.
This person didn’t even have an air cleaner that fit the car correctly on it. When I brought it home I looked at it and the element had about an inch of space above it where it didn’t touch the top of the housing. Air and dust could just go right over the top of the filter and into the engine. I bought that edelbrock air cleaner because it fits the carb they had put on the car.
The plus is that the car has no rust and runs like a top until this.
Anyway the car has the regular block mounted mechanical fuel pump. Don’t know what the PSI is that it puts out,but what you say makes sense since it did it after I was on the freeway. If the floats bend under pressure sounds like that happened.
So I’m curious,what do you charge to rebuild a 1406? What regulator do you recommend? Where are you located maybe I could send mine to you. Or can you recommend a better carb for the 360 for a daily driver
