Turbo Cam on a NA setup?

Does anyone know how a cam made for turbo applications would act on a engine setup for N/A (generally)? Would it produce higher or lower hp gains as compared to a cam designed for a NA engine? Sorry 92cavquest just lookin for a second opinion

Specs are going to determine everything

well first off the turbo cam is built tougher and can handle higher rpms for longer durations so when you jam that engine so hard the lifters "lift-off" into space the cam will sit there and say "what? is that it?!"

Now i'm just going to speculate on this... not 100% sure if i am right on this, so chime in if i'm wrong.

both, the more lift and longer duration the more air can be moved, always think of an engine as a big complex air pump, the more air in and out the more power your going to make. if theres just more air coming in, then you might make a lil more power. if you just have move lift/duration on the exhaust side you will more then likely have better mpg's and might make a lil more power.
