Where is number 1 on the distributor cap of a 5.7?

On a 5.7 engine, number 1 on the distributor cap is typically located at the front of the engine, aligned with the rotor's position when it points to the number 1 cylinder, which is usually the driver's side front cylinder. To confirm the exact position, it's best to refer to the specific service manual for your vehicle, as configurations may vary slightly by model and year. Always ensure the engine is at top dead center (TDC) on the compression stroke for accurate placement.
