Hmmm... I wonder if this would be helpful all put in one, since we all tend to go all over the place to find sheets for each cam so here's a sticky. I was doing some studies about most used D-series cams on street/tracks last night and here's all the info in one... I am not saying these are all 100% accurate, but what the companies advertised otherwise. I won't bother finding specs of the regrinds since it might not all that accurate and i was mostly interested in billets.

Thank you for this information. What would be REALLY helpful is the engraving marks on the site of each cam for identification purposes.
