ESRI streetmap data not projected?

Hello,

I am working with ESRI streetmap data i.e. SDC data is in GCS_North_American_1983. I am also using the streets network dataset provided with the streetmap data which is also in same geographic coordinate system.

My question is wouldn't the results be right if the network dataset was built from a projected streets layer. The results would definitely vary if a projected network dataset was used. So should I create a shapefile from the SDC streets file, project it to North America Lambert Conformal Conic and then generate a network dataset.

Correct me if my analysis is wrong?

Thanks
