What's up with Comp Cams ?

If all aftermarket cams were wearing out at the same rate, then I could see this being predominantly an oiling issue. But since there are certain brands of cams that are holding up very well to today's oils, it makes you sit up and take notice. That was the whole purpose of this thread. It was not "why are all aftermarket cams wearing out so fast these days?" If that was the thread title, then you could turn this into an oil thread. But premature wear and improper intake centerline grinding are not oil related. Not if other brands are unaffected.
With that being said, I hope my comp cam hold up
And still nothing from OP.

I think the point is in a street car built for reliability and longevity, oil, as long as its good enough, won't make a difference. But a performance built engine revving to 7k is something else entirely. Because "good enough" is beyond what most oils provide.

Read the link I posted earlier. There are brands out there with less ZDDP and work beautifully because of their sheering factor. Look at what oil made #1. It only had 806 ppm of zinc compared to the rest. Its capability to protect against metal to metal contact is why it made #1. As I said before Valvoline VR1 10w30 conventional or synthetic is the best in my eyes. I do agree with you though on regular oil change intervals and so forth but no matter 100 miles or 3000 miles, wouldn't you want the best in there?

I would like to share a reply from Comp Cams to my questions about type of Material,Tolerances, and Concerns we normal folk have..lol.
Take note of the link at the end of the reply. hope this helps
Here goes...
"Hello Plustiano and thank you for signing up on CPG Nation!!!
Comp Cams uses various materials to make camshafts depending on what is best for that individual engine and application. We use a wide array of materials due to the fact that we cover a very wide variety of engines. Austempered cam cores are not used in LS applications nor have they ever been by our company. Our LS cams are made predominantly from 5160 or 8620 material. Either the 5160 or 8620 material is more than capable of handling any Hyd. Roller LS application. The difference in materials used has no effect on quality control what so ever and I am not sure what would lead you, or anyone else, to believe that it would. Also all of our cores are produced in the US and come from 1 of 2 sources. These are the same sources that sell cam cores to most every cam manufacturer out there, including the OE manufacturers. I can assure you that no “cheap” or overseas core is ever used in a Comp Cams product. When grinding a camshaft the core specifications must be as close as possible to the finished cam grind specs in order to maintain the deepest possible heat treat. That is why Comp has the largest selection of cam cores in the industry.
Comp maintains some of the highest quality control standards of any camshaft manufacturer in the world. Our cam grinds will be closer to the specs on your card versus any other grinder. We see less than 1% defect rates in our LS cams, which is lower than any other manufacturer that I am aware of. Also there has been no consistent heat treat issue of any type that I am aware of. This is not to say there has never been individual issues, but nothing that has been a continual issue. While it is certainly true that we are not perfect and we do encounter the occasional issue with one of our parts, we do try very hard to ensure that problems are very minimal and we have kept it at a level of less than 1% regarding LS camshafts.
Tolerances for our cams are:
Lobe Separation: +/- 1 degree
Advance: +/- 2 degrees if specified
Duration @.050: +2.5/-1.0 degrees
Lobe Lift: +.003/-.004
We do care about our customers and their projects because we rely on them for our livelihood. We strive to make the best performing and the longest lasting product possible. No company is perfect, but we do try. Also, if a customer has a problem with a product we do everything we can to help fix it.
I would also like to direct you toward a press release put out by Driven Engine Oil. It highlights the importance of proper engine oil especially in LS engines.

Looks like I will either buy a degree wheel or see if someone can loan me one for my cam swap.

To be honest I never contacted them about the matter but I am more than sure they would not the part that have me so angry is this is from a previous fresh build which I spent thousands of dollars only for this to happen the cam was great performance wise it was a stroker V.3 247/251 but the word around is how comp cams has Ben causing a lot of people the same problem I will just have to take it as a loss and lesson learned.
