If you Tribute a face-down Dragon for "Strong Wind Dragon", it will still get its ATK boost.
"Strong Wind Dragon" gains half the Tributed Dragon's original ATK (in the GY), not half of the Dragon's ATK as it was on the field.
"Strong Wind Dragon" will get its ATK boost even if you Tribute a monster that was treated as Dragon-Type because of "DNA Surgery".
