The 707 is a lighter airplane than the trusty DC-8, structurally. That means that it requires a good deal more effort to keep it airworthy. The 707 is also subject to more corrosion than the DC-8. Given the higher costs of keeping the '07 in the air, and what may well be higher systems maintenance costs, it doesn't pay to reengine it in most instances, for instance.
