I totally agree. When I started this thread it was because I kept reading that LSA doesn't effect idle quality when I KNOW it does. LSA has a larger effect on idle quality than duration does. I also wanted to dispell the notion that cubes "eat" duration--totally false as well. When I decide on cam timing events I take into consideration so many aspects of the build from the hard parts to the totally subjective aspects it would take a long time to put pen to paper. I do have a bit of a "system" but its more based on experience and it wouldn't translate to paper well at all. J.Rob
