You shoulod want around 52 degrees total timing. Since most factory vacuum cans make 15-16 degrees of ADVANCE (not vacuum), 36 degrees of inital and mechanical would put you in the ball park with 15 degrees of vacuum ADVANCE. To solve your pinging, either reduce your initial, limit your mechanical, or adjust your vacuum advances. Your engine is no different than any other when it comes to timing.
