The horsepower of a stock 5.7L V8 engine depends heavily on the *make* and *model* of the vehicle it's in. There's no single answer. Different manufacturers tune their engines differently, resulting in varying horsepower outputs.
To find the horsepower for a specific vehicle, you'll need to specify the year, make, and model. For example, a 2023 Ram 1500 with a 5.7L Hemi will have a different horsepower rating than a 2010 Chevrolet Tahoe with a 5.7L V8.
