L92 vs LS3 Questions

I am considering doing an LS conversion and would like to use an LS3. I have been trying to compare the L92 and LS3. I looked through the dyno posts and don't see many people using an L92.

If I were to upgrade to an LS3 intake and fuel injectors, VVT delete, then add a cam, would the output be same or close to the output of the LS3 with the same cam?

Thanks. I had read that. I thought it would allow higher RPMs and potentially higher peak numbers. What affect would they have at 5000rpm on each engine. Any difference in performance at the same RPMs?
