| Experimentation is the only way. |

You can start from base settings that are just that...a base from which to start.
The general safe base settings are 12 degrees initial and total of around 38 degrees. This is with no vacuum advance.
But it's not quite that simple (and it never is). What timing you can run depends on everything about the engine and the car. What you have right now are a starting point (initial timing) and an end point (total timing). The middle is the centrifugal advance rate and this more than anything will affect how your car actually performs. The factory centrifugal advance is rather lazy. With a fairly light car, steep gears, a healthy cam and compression, you'd want the centrifugal to come in fast and early. Though it's not too difficult to alter the advance curve yourself, it's a good idea to have a professional set up your distributor for this.
Ultimately, you want all this to occur without detonation.
