For some understanding and some basic math concerning rod length and stroke there is a member that has written and published some very good articles. The math is explained as well as the technical engineering stuff. These are copyrighted and his own product. But he has made a lot available for us to read. Look up Panic in the member list for more about him. This is a link to a paper on rod length and stroke. And why it matters.
