* Year and Model: The spark plug gap can vary depending on the specific year, model, and even the engine modifications of the 440.
* Spark Plug Type: The type of spark plug you're using will also impact the gap.
* Manufacturer Recommendations: The most accurate information will come directly from your vehicle's owner's manual or the recommended specifications from the spark plug manufacturer.
Here's how to find the correct gap:
1. Consult Your Owner's Manual: This should have the recommended spark plug gap for your specific 440 engine.
2. Check the Spark Plug Box: The packaging for your new spark plugs will often list the recommended gap.
3. Contact Chrysler or a Reputable Auto Parts Store: If you can't find the information in your manual or on the packaging, you can contact Chrysler customer service or a reliable auto parts store (like your local NAPA or AutoZone).
Remember: Always double-check the recommended gap before installing new spark plugs. Using the wrong gap can lead to poor performance, misfires, and even damage to your engine.
