I just finished doing this to my 64 SS Impala. It has ran rough since I bought it but I lived with it like you until last weekend. I bought a new cap and rotor and installed. I found 1 bad wire and replaced it also. I then started messing with the carburetor and found the vacuum advance was hooked to the ported side passenger side of the carb so I swapped them. I then hooked the vacuum gauge up and fine tuned the 2 idle air screws to get max vacuum and it's running great now.
I do need to buy a new set of plug wires and plugs for it though but for now it's fine.
