Someone recently posted that I had once made a timing pointer for my distributor.
It is shown here:

I found that this was very accurate for adjusting my timing.
When I lived at Santa Fe at an altitude of 7200 feet I found that I could advance the distributor anywhere and not get pinging.
At high elevations I found that advancing the distributor gave me much more power.
So I would have it at 25 degrees in the mountains but would have to lower it when traveling.
When I got down to, say 3000 feet, I would drop it to about 15 degrees. When I got to California close to sea level I would put it at 8 or 10 to prevent pinging.
This was all before I had a fuel injection controlled distributor with spark control.
I no longer use the original distributor.
