The initial timing for a 1972 small-block Chevy (SBC) 350 engine is typically set between 4 to 12 degrees before top dead center (BTDC) when using a vacuum advance. However, the optimal timing can vary based on engine modifications, fuel type, and overall engine condition. It's best to consult the specific vehicle's service manual or timing specifications for precise settings. Adjustments may be made based on performance preferences and engine tuning.
