The power output of an engine is not solely determined by its displacement (cc); it also depends on factors like design, fuel type, and tuning. However, a rough estimate is that a 420 cc engine might produce between 20 to 50 horsepower, depending on these factors. For example, a small motorcycle or lawn equipment engine might be on the lower end, while a high-performance engine could reach the higher end of that range. Always refer to specific manufacturer specifications for accurate horsepower ratings.
