For a 1979 RV with a 440 engine, you typically set the timing mark at 5 to 7 degrees BTDC (Before Top Dead Center). It's important to refer to the specific service manual for your vehicle, as timing settings can vary based on engine condition and any modifications. Make sure to adjust the timing while the engine is running at idle for the most accurate results.
