That '32 five window sure looks like Harry Luzader's car. There's a lot about the car that looks right on the money and the fact this film is in Pennsylvania where he's from.
Amazing video! Can't shed any light on the track, but we'd agree with @Rolleiflex...looks like the Luzader car after it moved up to B/G (with the headers routed out by the cowl).
I think that's Harry's car when he first started racing it. At that time, it had what we referred to as a "352" Cu. In. motor. He scattered that motor there, at Quaker City. The lady, near the end of the film, I think is Larry's Wife. She was very busty.
