I have to chuckle a bit here.
Comp are the "bad guys" here because the can't determine by looking at pics taken with a phone whether or not there is an issue with a cam.

@Fast & Laroy, Not sure who the comments were intended for but you did reply to my post...??? I personally never said they were "Bad Guys", maybe you're referring to comments from others. But THEY did allow a questionable camshaft to be released from their facility. I certainly did not expect any miracles from them simply viewing the pictures. I was hoping that they would possibly come back and say that the black finish would wear off normally and its okay to run the cam, we checked the records for Nitrided process on that day, we reviewed it with the Engineer etc etc... But I had a feeling they were going to tell me to send it back. So they are trying to make it right. However, regarding their comment about how they are "unsure how it made it past quality control". My opinion is that it should not have made it past QC unless there is truly no problem with the coating. And if that's the case, I would only assume and hope that they (Comp) reviewed all this before returning my phone call. I paid over $300 for a flat tappet Hyd cam from them that is now questionable. Im certainly not the bad guy here.... I appreciate the help and info from all on this board. Thank you! Im just in a bad spot at this point with the camshaft and current timing, I need to get this project wrapped up. 2017 is going to be a very busy year for me and I will have NO time to work with the engine or car. As I stated earlier my goal was to get this completed before the end of the holidays. That seems to be at Jeopardy at the moment. I need to decide if I want to risk it or revisit this in about 6-8 months when more time is on my side. Thanks again, Merry Christmas and Happy New Year's to all!

IMO, at this point it's only "questionable" because you don't think it looks right.
They have a QC dept, and someone there gave it the nod of approval. Does that mean it can't have a problem? Of course not.
But they're doing all they can to satisfy your misgivings by having you send it back for them to look at again.
My previous comments were more directed at the "pile on" from some others on this thread.
My experiences with Comp are in line with Jim's. Mistakes happen from time to time, and I have always had them taken care of as well as could be expected.
In the end, it's your motor so you should do what you feel is necessary to make sure the parts going in it are up to your standards.

If the nitrading causes the cam to be black like that, how come the bearing journals are not black

I had a crank nitrited and it was sorta dark but all the journal were shiny.. I would have to guess that the crank shop polished it.. that crank is in one of my SB right now

If the nitrading causes the cam to be black like that, how come the bearing journals are not black they were either polished after or protected from the process. Nitriding causes a flat black surface...think like case hardened hardware. I grabbed this pic off the internet....I don't have any pics of the one I had done. look particularly at the snout.

My gut feeling is anything that can be scratched off easily is a surface coating. Like above said Except that if that was the case Comp would have stated so after looking at the pics.

My gut feeling is anything that can be scratched off easily is a surface coating. Like above said I would have to agree with this basically. I had my cam nitrided and really dont remember just how it looked but I do know most new flat tappet cams I look at seem to have a black surface on the lobes when new even if not nitrided. Myself I was told nitriding is a hardening of the cam and I really cant see that being a surface coating that could rub off. I bought my custom grind cam from Dwayne and he told me Comp did the nitriding on it. And I can tell you its been in my eng since I fired it up in June 2011 and is still going strong and has not wiped any lobes or had any problems at all. If I were you and I was worried about it I would send it back to Comp and let them look at it as even if they say its fine that will give you peace of mind. Comp is stepping up to the plate and doing what they can. And I agree with them that its tuff to tell by just pics whats going on. I feel its a surface coating like was said maybe for rust prevention because as I said I cant see a hardening process as nitriding rubbing off with your fingers. It will most likely be fine but why not send it back and let them make sure its right ? Everyone can and does make mistakes and if they did the right thing to do is step up to the plate and make sure its ok and correct it if it is not and Comp seems to be stepping up to the plate if they did make a mistake which is the best anyone can do.
