It's a question of engine noise. The DC-8s that you see are the
re-engined/stretched versions. I think it was the -60 series. Boeing made
the strategic decision not to re-engine/stretch the 707 (though they looked
very hard at it). They did re-engine the military versions but choose not
to certify the changes.
