The problem with the theory on degreeing a cam so that you can run it "straight up" or "advanced" or "retarded" a specified amount of degrees is that it is only accurate up until you start the engine for the first time! You have immediate timing chain stretch. And after just a few runs on the quarter or a couple hundred miles on the street your cam is "off" by quite a few degrees from both where you set it and where the cam manufacturer specified. So what's the best solution? Don't really know. Usually though, if I have an engine that I am serious about running "straight up", I will advance the cam 2-4 degrees when assembling it. That way it's closer to 0 after it has run a bit. However, it's only a band-aid approach, as I've seen good quality timing chains stretched 6-8 degrees after only a few hours racing. You can also use only "used" timing chains that have allready stretched and degree it and put the appropriate advance or retard to set it at 0 when assembling your engine.
