the timing and porting of the engine have nothing at all to do with getting more speed from the same said engine,

Hate to tell you this but guys have been modifying and running engines well past their designed rpm limits for many years. If YOU are having trouble doing it, then you are doing something wrong, try mixing your own fuel with quality ingredients. No matter how hard you try to manuever around your infamous quote, it isn't gonna work. There are only so many guys as gifted as Bill Clinton at doing that sort of thing. Your analogy of the higher revving .21 being slower than the .60 on the same ship isn't much news to anyone here, I'm afraid.
