boyo here's what Clifford says:

"Several years of research and testing proved that a small displacement inline 6 cylinder, properly modified, would produce equal and, in some cases, more useable low RPM power than a large displacement V-8 engine"

You know, the more I read it the less impressed I am. How small a displacement inline 6 against how large a v8? The statement is ambiguous, but at least it markets (and sells) well.
