Engine assessment

[Model A Man]

I have a 31 deluxe roadster that we just drove in a parade and it started acting up and wouldn’t idle and making strange sounds like either the throw out bearing or alternator bearing is going out and also started a knocking sound. I don’t know much about this motor, who built it etc. other than it is a inserted motor. I also am planing like the original poster to pull the motor and trans to take them apart an inspect everything and replace and repair what is needed.
