Thought I'd post an update. I'd like to throw out a huge thank you to Martin from Tick Performance. He has been there every step of the way for this issue and made sure that my cam got warrantied. He got me new gaskets at cost and got them to me fast. He answered all my questions and concerns quickly and thoroughly. Comp overnighted me a brand new cam once they got it ground. Got 60% of the swap done Saturday and finished up the rest tonight. Crossed my fingers and... NO WHINE!!! I did new gaskets, new retainer plate, new gm retainer plate bolts, arp cam bolts, reused my 1500 mile ls2 timing chain and arp balancer bolt. Only drove it around about 10 miles but I did let it idle for 12-15 minutes first to top off coolant with 0 hint of a whine during the whole process. Last time the whine was there immediately. Been a long day so that's all I'm going to post for the time being but again, thanks Martin@Tick and thanks Billy@Comp, you guys made a crappy situation much much better!
Guess to any doubters your post has now proven 'IT IS THE CAM'

Hey Dan! I appreciate that man, heard a lot about you and the car. Alex said you and I put down similar numbers on Dan's dyno considering our mods so that made me feel better about his stingy dyno haha. Here's hoping Alex's doesn't whine... Dang thing has been apart for longer than it was together lol.

Your cam was brand new and not just repolished?

Just spoke to greg, my cam will be here tomorrow and I will throw it in Friday most likely.
He said everything was well within specs so we shall see if just the polishing did the job.

Roads cleared up today, I took the vette to work. I still haven't tuned the car yet, but it's probably pretty close.
Got on it a bit and it has freaking loads of torque. I guess from filling the cylinder 5 degrees btdc and then closing the intake valve fairly early at 41 atdc. I'm glad I advanced the cam when I installed it.
I can't imagine how torquey it will be with headers.

Up date on a cam that was whining. We received a cam yesterday for inspection and polish. I was wrong about the fine CHATTER it was not fine it was very visible to the eye. Very fine Chatter can still cause whining. It still hard to see if you do not know what you are looking for. The light has to be good.On this cam you could feel it and see it with no problem. After a polish job it looked good to go with out any problems. We shall see.

Just went and picked it up.
GOOD NEWS!! No whine at all when i ran it for about a minute.
I have to get the water pump, crank pulley, radiator and a coil/plug wire issue Im having solved so I can run it more and put it through its paces before i say its fixed 100%.
Which hopefully should be tomorrow night. Ill post an "after" video as well.
