I just had my 327 rebuilt and I can't seem to get it running right! 1964 small journal motor, 40 over, 280h comp cam, 461 heads with 1.5 intake/2.02 exh, 4bbl with eldbrock carb, petronics ign with a new coil. I have only have about 4 hours on the motor. It will not idle below 1500 rpms. The advance is @ 40 deg with 15lbs of vacuum and the timing is all over the place. I can't find any leaks on the intake or carb. The valves are all good and set What am I missing. The engine has been jacking with this all day and I am so ready to shoot this engine. Any help or direction to start in would be great.
