I just did a cam swap in my 2000 Firebird this weekend have have to comment on how clean the engine was.
I have been useing 0W30 since about 600 miles and it now has 40K miles. No issues at all with oil consumption. I'm not easy at all on this car, it's seen around 150 1/4 mile passes, about the same amont of AutoX passes and a crapload of play on the street and the N.Ga. mountains.
The guy that did the cam swap {don't worry, I was watching and learning
} commented on how clean the engine was and how good of shape the timing chain was in, said it was a shame to replace it with the new one. Really, there were no deposits at all, not even the reddish-brown deposits that wipe off.
Very happy!
