I am new to the Ford world. I have a '65 mustang that has a '70s 302 with points ignition (I Guess have not run the numbers). I have a feeling because of the way that the vacuum advance is facing and the stretch on the vacuum I belive that it is about 180 degrees out. Can some one get me what it should be set to?

 

It's been a while but 13degrees sticks in my head... thats a good starting point at least.
