....As for run of the mill cams made from blanks that they purchase elsewhere, they still do the grinding, dressing, acid treating, polishing and hardening so although they may not produce the raw casting, they do make the cam.
You've missed the point.
Call it what you like, although in the domestic manufacturing world that I live in, making has a very specific meaning and not to be confused with processing and finishing. But it's really unimportant.
The point was, and still is, until there are data that shows Comp's cams have a higher failure rate, and the root cause of the failures, its meaningless to view Comp Cams in a different light than the rest of the cam suppliers.
I'm not tell you to like it. I am saying it is what it is.
Here is an opinion based on observation in the manufacturing world: The casting of cores for the aftermarket for 50 year old engines is very very insignificant in CWC's world, and any other foundry with any meaninful production capabilities. It is clearly the bottom of their priority. They probably don't even make margin. On the other hand, a significant part of Comp Cams business is selling us cast cams for the aftermarket for 50 year old engines. For their respective roles, my money for product/process QA/QC is on Comp Cam over CWC.
Again, all cam suppliers have failures, the failures may, or may not be due to the cam, the failures that are cam related, are likely do to a combination of both the foundry quality and the grinder/finisher quality.
It will interesting to see where this ends up. It's hard to believe that it won't get worse, and the cost goes up. If you want to avoid cam failures, you will need to move away from flat tappet cams.
