Generation IV Internal Engine - Anyone have LS3, L92 and LY6 factory cam specs?

I want to pick one of these engines for my 67 project and was curious the difference between them all. I am betting the cam and compression. I know the LY6 is an iron block 6.0. Anything else that would help me?

go to GMperformanceparts.com and download their catalog, they have them listed in there.
