If I remember correctly, the Hotcam didn't make as much power as the second LS6 (MY 2002) cam did. If I remember correcly, didn't the LS6 have more lift and a little less overlap and LSA?
I agree that GM wouldn't get a Hotcam into an OEM car but I'm sure they, if not many other companies have custom grinds that will give good power. To me though, GM engineered the engines as a package, and operate within a certain range. Typically, adding a cam will change the operating range in order to achieve maximum power, and sometimes that range goes outside of the parameters the engineers went by. Anyhoo, I'd prefer to keep things nice and simple and stay out of the long block.
To each his/her own
