it should also be noted that early SW7s looked much like
late NW2s except for the large full front radiator.
and late SW7s looked rather like SW9s except for some
louver changes on the hood sides.
the SW7 was always rated at 1200 HP no matter which phase it was.
Edit- Jason,what a difference 1 missed word can make !!
thanks for reminding me.
not sure when the change from radiator hood top louvers to screens
was exactly,but that was a bit after SW7 production started.
