* Engine Variations: The 350 engine was used in numerous Chevrolet models and over many years. There are significant differences in engine specifications, compression ratios, and even the distributor used.
* Year and Model: The exact ignition timing depends on the year, model, and specific engine features of your El Camino.
* Proper Service Manual: The most accurate information about ignition timing is found in your car's owner's manual or a service manual specifically for your year and model El Camino.
Here's what I can tell you about finding the correct ignition timing:
1. Consult Your Service Manual: This is the best source for the recommended ignition timing for your specific El Camino.
2. Look for a Tag on the Distributor: Some distributors may have a tag that indicates the base timing. However, this is not always reliable.
3. Use a Timing Light: A timing light is a tool that allows you to see the spark plug firing and determine the timing. You can purchase one at an auto parts store.
4. Professional Mechanic: If you are unsure about any of these steps, it's always best to take your El Camino to a qualified mechanic who can properly diagnose and adjust the ignition timing.
Remember: Incorrect ignition timing can lead to engine performance issues, reduced fuel efficiency, and even damage to your engine.
