Ford 391 2bbl carb jet sizing

It runs perfectly now with now hesitation or popping/snorting and wheezing like it had been doing.


I am very grateful for all the advice shared and given. Thanks guys.

Hello, I am a new member to this forum. I realize this is an old thread but you seem to have the same components on your engine as I do. 391 IND with 2BBL Intake, Motorcraft 2100.
I'm having some of the same issues you described but already replaced all the items you listed. Did you keep the #57 Jets in the carb? Do you have a governor on carb or distributor?
I originally had the 330 and swapped out for the 391 but kept the 2bbl intake. Afraid I ran it to lean for too long already.
Also, what spark plugs do you use?

Welcome to the Forum. Since this is a pretty old thread, you may want to click on the members avaitar, or name and then you can find out if you can send them either a privite message or an email. That's a nice looking engine!
