That's a tough question to answer. There are many variables involved that will determine what kind of timing your engine will like. Your cam manufacturer can recommend a general setting. From there, you can advance the timing a few degrees until you get some detonation. If you're running an advance curve in the distributor, get the advance to come in as fast as possible before this occurs.
