Question: what is a 5.0 engine?
Answer: The figure refers to the rounded-off displacement of the Mustang's pushrod V8 during the early '80s to 1995. Now, for the first time in a decade the "five-oh" is poised to return. Let's take a closer look at the new engine. The original 5.0 V8 displaced 302 cubic inches, or 4.948 liters.
