I have a 57 Bird with a 312. It has one of the Holley 465 replacement carbs on it that's about 6 months old. This car has always had a lopey idle as if it had a small street cam in it. I had a guy at a car show this weekend told me his Dad's 57 idled smooth as a new car today. If you knew me, that got me working on the tune. It's rough enough at 800 RPM you can feel it in the steering wheel at stoplights. I always considered myself as pretty good on Holley carbs but I cant change the idle of this thing no matter what I do. The car runs great off idle. Question is, Was that guy just full of Shxx when he told me that? How smooth of an idle should I expect? I've never listened to another one run so I'm kind of shooting in the dark. Thanks!!
