Default Turbo and emissions?

I have a 384 with a cam that is on the edge of emissions as it is.
What would adding an STS setup do to emissions?
Do I need to swap for a smaller cam?

If anything, it will lower emissions. Worst case scenario, it would make no difference at all if you changed nothing else. I'm assuming that you are already catless.

The STS kits are supposed to be pretty good with emissions. As far as swapping out cams, that just depends on the duration and overlap of your current cam.

I should have explained the setup a little more.

The car does have cats and no headers as per emissions laws. The duration is 226/230 117+1 lsa 6* overlap to pass emissions in the 384 stroker (Patrick G grind). 8.17 DCR 10.86 total compression. Obviously, it isn't built for a lot of boost, but that isn't what I'm looking for. If I could tack on 100-150 extra horsepower, I would be absolutely thrilled.
