Does someone know what if any differences there would be between the Rochester 4GC 7024054 and 7024055? Looks like all the settings are the same and they are both specified for year 1964.

I'm thinking about getting a new/rebuilt carb, mine is kind of hatched out and I want to increase my odds of finding one that is specified for my 1964 F-85 330 4BBL High Comp.

Thanks

 

I have packed my Rochester carb parts manual away for a move, but odds are the difference will be stick vs automatic or sometimes airconditioned vs. non-air. I have also seen high-altitude carbs have different numbers. The differences will be in jetting or sometimes a/c carbs have an idle compensator vent, but I think most all 64 330 carbs had that.

I think Joe P bought one of those manuals during his recent swap meet jag, and he has a Jetstar 88 so the carb app will be the same.
