I won't be running power steering. I haven't actually hooked everything on yet but I did do a "test fit" and everything seemed ok. I know that my old 292 was stock with a bit of off-alignment. Mine had the double groove dampner and the single groove water pump pulley. Most C10's didn't come with p/s so that's a very common setup. The 292's in the big rigs sometimes had a 3 groove dampner and water pump pulley.
