How do you set timing on a 327 motor with hie?

To set the timing on a 327 motor with a High Energy Ignition (HEI) system, first ensure the engine is at top dead center (TDC) on the compression stroke for cylinder number one. Then, connect a timing light to the battery and the number one spark plug wire. Start the engine and aim the timing light at the timing mark on the harmonic balancer; adjust the distributor until the timing mark aligns with the desired advance specification. Typically, a timing of around 8-12 degrees BTDC at idle is a good starting point, but refer to the specific engine setup for precise settings.
