* Engine design: Different manufacturers have different designs, leading to varying power outputs even with the same displacement.
* Year of manufacture: Engine technology improves over time, resulting in higher horsepower for newer engines of the same displacement.
* Aspiration: Naturally aspirated (no turbocharger or supercharger) engines will have less horsepower than forced induction engines (turbocharged or supercharged).
* Tuning: Modifications to the engine can significantly alter its horsepower.
A 4.3-liter engine could produce anywhere from 160 hp to over 300 hp depending on these factors. To find the specific horsepower of a particular 4.3-liter engine, you need to know the make, model, and year of the vehicle it's in.
