I don't see any reason the 317s and ls6 stuff can't handle as much as you can hit it with however the zo6 cam will only flow well enough to get to 6-700hp you will want more cam eventually and you might run into valve float without better springs. Brian tooley platinums would be an excellent choice. Seems like a great build with a ton of funs parts. I think the speed inc TU1 boost cam that 02camaross uses would be perfect for this build.
