Soooo...
Is the L99 pump any different than the Ls3s?
Has there been stock oil pump failures of L99s with cams? Dont think an LS3 conversion is Required for All cams (VVT?)
Seems to me the pump could still fail as a result of a cam failure on a L99.
Also (mentioned in one of my other threads):
Any reason besides cost why one shouldnt run a higher zinc oil such as the Joe gibbs LS30, even if the car isnt cammed (stock internals)?

This is a good question because I can only think of one L99 oil pump failure from this site in 4 years. There have been many LS3 oil pump failures reported and yes the L99 and Ls3 oil pumps are different.
