this made me think of a thread from another site I read last week. It took a while for me to find it but here it is. They end up talking about dynamic compression, static compression, valve timing, stroke, etc. My head was swimming after reading the whole thread. And these guys are "Old Skool" people. It just goes to show that most of us (me included here) don't even begin to scratch the surface of understanding the dynamics involved in what makes our engines run much less getting a handle on what it REALLY takes to improve upon what has already been designed into any particular engine beyond slapping a 4bl carb, intake and headers onto it.
