To determine the exact engine in your 1980 Impala, you need to check the vehicle identification number (VIN) or the engine bay.
Here's how to find the engine information:
1. Vehicle Identification Number (VIN): The VIN is a 17-character code located on the driver's side dashboard, near the windshield. The 8th character of the VIN usually indicates the engine type. You can use online VIN decoders to decipher the information.
2. Engine Bay: Look for a sticker or tag on the engine itself or on the engine compartment wall. This should identify the engine size and code.
By checking the VIN or engine bay, you can determine the specific engine in your 1980 Chevy Impala.
