GM Red Dot Cams???

[TX '90 ZR1]

There is a white/red '90 just listed on BAT.
The seller posted the following:
I asked the tech to check the tuning as there is a “flutter” at about 3-4k RPM at medium throttle. He said that given the mods that is to be expected, as all systems are functioning properly. In his words, the car is tuned to “run like a raped ape”.
He also said that he inspect the cams and the car has the GM Performance red-dot camshafts and also has some other intake modifications so that the intake temp stays cooler which were above my paygrade, but he said were the right upgrades for the car. Should be pushing 450hp.
Can someone explain to me what "GM Performance red-dot camshafts" are?

28 years of ZR-1 ownership, never heard of red dot camshaft. Doesn’t mean it doesn’t exist because I never heard of it though...

My post was with tongue in cheek.
I have not heard of them either. I haven't had what you would call extensive experience with the Z, but I owned my first one in 1990 and have always followed them.
I don't want to start a pissing contest in his auction, so I am going to leave it alone. After someone else questioned the cams, I did comment that there was a lot of inaccurate information about the cars. That's as far as I'm going with it.

And it’s up to $20k already... go figure. Bodes well.
