I have a fresh 460 installed in a 68 continental. After going trough the initial run in and a couple of small setbacks along the way. (Thanks to some of you) I am having another problem. The engine idles fine and sounds good, Timing and idle are set to specs. When I rev the engine or depress the pedal and hold it steady it begins to stumble really bad, and when I release the throttle it will keep stumbling and barely run and not want to idle. If I shut it down and restart it will idle fine untill I rev it high again. I still haven't driven the car as I am still doing other things to it but I am hesitant to try unless I can figure out what is amiss here. ....................Richard
