Perhaps it would tell you nothing except how to fit "Mr. Average", but a normal '70s aesthetic for that frame, would, IMO, be:
- seat about 1" farther forward, and level
- stem 1 cm or 2 cm longer
- brake levers about 1" farther down the bars
- bars rotated so the bottoms slope about half as much as they do now
With the high hoods and rotated bars, it looks like you are emulating more modern bars. Nothing wrong with that, as Seinfeld says. You could try the first and last items above without much effort. Maybe you don't need the other two. They would all basically shift your CG forward a bit. That will either feel better, or it won't.
