I wasn't aware that Chevy made a 366. However, I'm guessing you have a small block Chevy which is pretty much the same on timing, no matter the size. Generally speaking, around 7 degrees @700 rpm should do well. Depending on application, this could vary, but if your vehicle doesn't have an emissions sticker, it's a good starting point. I would set it there, then test drive it. I would continue to advance the timing, in one degree increments, until you encounter pinging under heavy loads or acceleration --- then back it back off. This will generally give you the most advance possible - which improves not only power but economy as well. Hopes this helps out.
