Could the high pitched noise be a "dry" belt? Does it vary with RPMs? I'm now leaning away from the starter. My reason is, if it made the noise while cranking and continued while running, then the starter is more suspect. However, you stated the noise only began after the engine fired. So, this eliminates the starter. If the starter gear did not disengage and was being driven by the flexplate (?), then I would think it would get pretty beat up. So, I don't get a sense, of this as the restarts seem fine. Does the car run rough? The backfire through the carb, sounds like a timing issue, with the noise being a vac leak. Is the noise rhythmic, or coming from one side or the other? With the engine running, certain sounds like ticking, can indicate a loose lifter pre-load (hydraulic). Squeals, can indicate a bad bearing, alternator, water pump, or dry belts. etc.
So, can you better define the "high pitched noise"?
