I' am sitting here looking at my monitor and I can feel my heart rate increasing. I know this post belongs in a different thread, but I can't resist. Is it the fact that a lot of gearheads were so bored in shop or other science classes we forgot how geometry works? Let's not even get to the physics part of all our engines. I just got off of a website for Stahl Headers that a member here recommended. Needless to say, i have never seen such an atroscity of misnommers and false information. Please understand, If you have a budget constraint, run what you can afford. If you have the opportunity to do it better, by all means do it. Somehow the "Experts" on the websites that a lot of people go to have this magical theory of a connecting rods "knowing" and "growing when it's required to do so. Wouldn't it make sense that every engine build we attempt would mysteriously do it's job because the parts knew how to do so? Somewhere along the lines in the 21st century we have failed to quit believing myths and snake oil salesmen. Geometry and physics are constant and no amount of BS or magic will change that. My point of this rant (moderators can remove for their own sanity and piece of mind) is to explain the simple rule of rod length not growing and shrinking at will. The base circle is always a base circe. 1 + 1 is always 2. The only constant value of any number is still 1. The piston dwell is the same at the top of the cylinder as it is at the bottom. Ring speed as it chatter's it's way down the cylinder and back up would destroy this engine if it had a different rate to follow. Piston loading can alter it's course as it pleases? NO. Somehow the novices who have all the answers have convinced those who ask good questions that the world of physics has an alternate universe in which it lives. Does anybody really think that the reciprocating pieces can tolerate such actions? Argue all you want about this phenomenom, Then do something really basic and build the same model out of acrylic or wood that I have to do to teach these courses or what ever and prove the point. Look at the side load angles the speed of which the piston arrives at it's cross over point and returns to it's equal and opposite direction. I'm here to rant for those who really want to learn and those who really desire answers with out spending years to acquire the degree that turns your mind into a gummy bear jelly like state. When good people here give you info, don't take it for what we said (even mine, especially mine) do the research. I thought that's why this site was put together. Please don't just run off and do what is ever the easiest. All budgets allow for good thought and setting your idea in motion. Now, I will go and find my place under the rock and I just stocked the fridge.
