To find the information you need:
* Check your owner's manual: This is the most reliable source.
* Search online: Use a search engine like Google, Bing, or DuckDuckGo. Search for "[Year] Chevrolet [Model] 4.3L V6 specs" (replace "[Year]" and "[Model]" with the appropriate information). Look for reputable automotive websites or forums.
Without knowing the specific year and model, I cannot provide the correct torque rating.
