* Ford 351 Windsor (small-block): The firing order is 1-5-4-2-6-3-7-8.
* Ford 351 Cleveland (big-block): The firing order is 1-3-5-2-4-6-8-7.
To find out which engine you have, you can:
* Check the engine block: Look for casting numbers on the block itself. These numbers can be used to identify the specific engine.
* Check your vehicle's documentation: Owner's manuals or service records may specify the engine type.
* Look at the valve covers: The valve covers might have markings indicating the engine type (though this is less reliable).
* Consult online resources: Websites dedicated to Ford vehicles or engine identification often have resources to help determine the engine type based on visual cues or casting numbers.
Once you know whether it's a Windsor or Cleveland, use the appropriate firing order above. Remember that the firing order is crucial for proper engine function. Getting it wrong can lead to poor performance or engine damage.
