Muscle car definitions?

In the "Strict Definition" at the bottom of the page it says "only...equipped with a large V8", yet they consider the Z-28 Camaro a muscle car. The original Z-28 was a 302 and the later models were 350's.

From their list, the basic definition seems to be 'if it came with a badge package'... :-k

They say they classify the AMX as one because it's based on the Javelin (which they spelled wrong - lol), *then* turn around (on the next line!) and say the Javelin ISN'T one...
