If the Chevy V8 is only 5.0L, don't know what the power output curves will be even adding 2 extra cylinders to be equal.



Displacement doesn't really tell the entire story. Also look at weight and physical size. Then look at fuel efficiency.

I don't know the numbers of each of the engines we are talking about, but power/liter is a somewhat defective measure of an engine's efficiency when looked at alone.


Well said, Justin. I like the concept of "power density" that is used to describe batteries. It describes how much power is produced per unit of volume and mass. The idea is to produce as much power as possible from a motor that is physically compact and light (the displacement may or may not correlate to this measurement).
