Here is a detailed list of Cams that came with the cars.
Corvette LS1
97-99 Duration 199int/207exh Lift .472int/.479exh Lobe 117
00 Duration 198int/209exh Lift .500int/.500exh Lobe 115.5
01-03 Duration 198int/207exh Lift .467int/.479exh Lobe 116
F-Body
98-00 Duration 198int/209exh Lift .500int/.500exh Lobe 119.5
01-02 Duration 196int/207exh Lift .467int/.479exh Lobe 116
So as you can see there has been basically very small differences in cams. The 01-02 is basically the same.
To answer some of your question 32valve. The vettes dont make more hp. There are equal to the F-bodies and sometimes actually make less power, because the independant rear suspension robs some hps. The differences are actually just weight. F-bodies are only about .2 behind the vettes on the 1/4 with everything being equal(not including ZO6's).
The GTOs rated at 350hp where jsut actually given the proper rating. The F-bodies where underrated by about 30hp. They should have been rated at 350 also. The speculation is that the vette owners would get pissed and GM would lose some long time vette guys. Dont know what made them change there minds with rating the GTO correctly. Maybe they discovered it wouldnt matter.
Also i just wanted to let you guys know that LS1tech just opened up a new Forum site for the mustang. Here is a link to it, you should go and check it out.
