Look at that artical in Hot Rod about the original Ram Charger car. That's a perfect example of optumizing the charge velocity to the engines performance curve. It was primative but it worked. I love the tuned fuel filler hose runners on the manifold. Great idea and easy to cut to length. Flow rate is velocity times the area. Match the charge velocity to the rpm and cid and the cyl. will fill faster and "pack" in more air and fuel. It's not so much the area but the velocity for two reasons. One, the time it takes to move the air/fuel mix into the cyl. to fill it at the given rpm and two, the pressure drop to keep the fuel suspended in the stream. If the velocity is too low the fuel falls out (condenses) into the runner and if the velocity is to low the cyl. isn't filled properly.
