* Engine design: Different manufacturers have different designs, leading to varying power outputs even with the same displacement. A naturally aspirated engine will have significantly less horsepower than a supercharged or turbocharged engine of the same size.
* Year of manufacture: Engine technology improves over time, leading to higher power outputs from similar sized engines.
* Specific model and application: The engine's intended use (e.g., a high-performance car versus a pickup truck) drastically influences its horsepower rating.
A 5.7L/350ci engine could range from under 200 horsepower in an older, less powerful vehicle to over 400 horsepower (or even more) in a performance application. You need to specify the *make, model, and year* of the vehicle to get a precise horsepower figure.
