How much horse power comes in a Chevy caprice 350 engine?

The horsepower of a Chevy Caprice with a 350 engine varied significantly depending on the year of manufacture and the specific engine configuration (e.g., carbureted, fuel-injected, modifications). There's no single answer.

You'll need to specify the year of the Caprice to get a more accurate horsepower rating. Even then, the actual horsepower might vary slightly due to manufacturing tolerances and engine condition. You could find this information in owner's manuals or automotive resources specific to that year and model.
