The horsepower of a Chevy 350 V8 varies significantly depending on the year of manufacture, the specific engine configuration (e.g., the carburetor vs. fuel injection, the camshaft, and other modifications), and its condition. There's no single answer.
A stock small-block Chevy 350 from different years ranged from approximately 155 to 300 horsepower. Highly modified versions can produce far more.
