N/A vs Turbo Cams?
Just wondering, what is the the difference between then? What would happen if you ran turbo grinded cams in an N/A car, and visa versa?

lol, maybe, but i would like to know what's do special about turbo cams and how they affect N/A performance

A turbo cam would lose power in an N/A engine. It all depends on the cam profile though. Turbo cams generally have a shorter overlap period and duration for a good reason - to minimize reversion back through the intake side on a turbo engine. In an N/A engine, you need overlap and duration to help bring in some fresh air on the intake stroke. While the exhaust valves are closing, the intake valves start to open and that's where the overlap is taking place. Longer duration on an N/A engine helps it to breath better at higher rpm while increasing volumetric effieciency. An N/A engine needs as little air intake restriction as possible through a good cam. It needs to make full use of the intake stroke by getting as much air into the cyl. A turbo cam does not have that profile. Because you are forcing air through a turbo engine, it's not necessary to have such a high overlap, long duration cam. Reversion is the biggest problem as well as a power loss.
