To find the correct firing order for *your* Chevy engine, you need to know:
* Engine size and type: (e.g., 350 small-block V8, 283 V8, 250 inline 6, etc.)
* Year of manufacture: The firing order can sometimes vary even within the same engine type across different model years.
Once you have this information, you can find the firing order in several ways:
* Owner's manual: This is the most reliable source.
* Chevrolet service manual: A factory service manual for your specific year and engine will contain the firing order.
* Online resources: Websites like the ChevyTalk forums or other automotive repair sites often have databases of firing orders. Be sure to double-check the information against your engine specifics.
* Engine casting number: The engine block usually has a casting number that can be used to identify the exact engine. This number can then be used to look up the firing order.
Example: A common small-block Chevy V8 (e.g., 350 cubic inch) often uses a firing order of 1-8-4-3-6-5-7-2. But this is NOT universal across all Chevy V8s.
Once you have the firing order:
The firing order dictates which cylinder fires in what sequence. The distributor rotor will rotate, sending the spark to each spark plug wire in the order specified by the firing order. This is why knowing the firing order is crucial for proper distributor cap wiring.
