For a 1988 Chevy 350, the ignition timing should typically be set at around 4 to 8 degrees BTDC (Before Top Dead Center) at idle with the vacuum advance disconnected. It's important to ensure the engine is at operating temperature before making adjustments. Always refer to the specific vehicle's service manual for the most accurate specifications, as timing can vary slightly based on engine modifications and other factors.
