Cams B16 or B18 on a B18head
this was something that i came across and saved but im not sure how accurate it is.
Recently I was looking for a good cam set for the application I am currently looking for and found a number of different lists for cam specs. The Japanese standard for measuring cam specs is @1mm which is, unfortunately, different from what some American brands like to measure at. I went through all the specs I had and converted them all to @1mm (except 3 I haven't done yet). This lets you do a much more accurate side-by-side comparison. I know there are a few other brands available (ZEX is one I just didn't put in, although I did know about it). If anyone knows any specs for sure that I have not included, please post and I will update the list!
