There's no single answer to "What size motor is a Chevy 5.0?" because "5.0" refers to the engine's displacement in liters, and Chevrolet has produced several different engines with approximately 5.0 liters of displacement over the years, each with different physical dimensions and characteristics. They may also have different bore and stroke sizes even if the displacement is the same.
To know the exact size and specifics of a Chevy 5.0 engine, you'd need to know the specific engine code (e.g., a small-block code like a 305 or a generation of the LS series). The 5.0L designation is a general description of the displacement, not a unique identifier.
