GM Red Dot Cams??? - ZR-1 Net Registry Forums

TX '90 ZR1 · 08-24-2019

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?
