I'm here alone today, tach is in dash. If I had to guess I'd say maybe 2000.
I ran it with the vacuum advance disconnected and it does not like that 20* at higher rpm.
2000 rpm is to fast for your specs. You probably want your total coming all the way in at 2500 plus.
Do you know what mechanical advance is in your distributor?
If stock unit without mods you could have 26 to 30 degrees mechanical advance you are adding 20 initial too. Not good.
