1965 chevy 327; ran fine for last 20 years; started it one day, barely ran, no power like running on 4 cylinders. Changed: electronic ignition, plugs, coil, distributor cap, rotor, fuel filter, fuel tank sock. Checked to make sure timing was in spec. Air filter not blocked (K&N). Still runs like crap; I am out of ideas. Help!!
It wasvthe carburetor!!! With nothing else left to change; replaced the Edelbrock Performer with a new one. With all the work done on this engine, it should run great and it does!! Thanks to everyone. Corv65
