LOL! I thought you were the square lobes guy. A lot goes into cam lobes and the spring pressures to control the motion. I never talk racing stuff, unless someone posts something real stupid. It does not interest me. I am a street guy that wants a fast car and only want to do it once, not have to dork with it for a long time and many, many miles. I don't care how an engine sounds as long as it will wind up and be fast. A race car is a completely different animal. What you are talking about is picking a lobe with the best area. The lobes are always a compromise.
