I went back to my previous thread as Charles suggested. When I read it a week or two ago I reviewed what I had on the car. The carbs had been set up by a professional mechanic who owns an original 427 and who does work for Jay Leno. The linkage was set as Charles suggested, and the recent note regarding the fact that the carbs are mounted backwards makes sense. But I am left with two questions. The first is the kind of change I would experience if I switched to 600 CFM carbs, keeping the progressive linkage. The second question is what kind of change would I see if I kept the 390s and used a linkage that opened both carburetors equally. Frankly that seems kind of foolish, since it seems to mimic a single 780 CFM carb with the two 390s, and it would seem to lose the advantage of sequential opening. But that is what it seems to me and I am not a carb person.
