Here's why, and how to find the information:
* Multiple Engine Options: Chevy Silverados in 1994 could have had several different 5.7L engines, each with its own firing order. The most common were:
* Small Block 350 (5.7L): This is the most likely option, and its firing order is usually 1-8-4-3-6-5-7-2.
* Small Block 305 (5.0L): While also a 5.7L displacement, this engine has a different firing order, usually 1-8-4-3-6-5-7-2.
* Your Specific Engine: To find the precise firing order for your engine, you need to:
* Check your engine block: Look for a casting number on the block. This is usually near the bell housing or front passenger side.
* Use an online engine database: Websites like AllData.com or Chilton.com allow you to look up your engine's specific firing order based on the casting number.
* Consult your owner's manual: Your Silverado's owner's manual should list the firing order.
Important Note:
* Always replace spark plugs in the correct order to ensure proper engine operation.
* Double-check the firing order for your specific engine before starting any work.
