1) SDs are intercooled from factory
2) HPOP on 99.5+ are 17* pump
3) Fuel is pumped by electric pump on SD
4) Injectors are split shot and flow more (1997 CA models had splits as well though)
5) AC Compressor and Alt are in swapped positions
6) The last years of SD 7.3s had powdered rods as opposed to forged rods
7) SD's use hydroboost brakes (no belt driven vacuum pump)
8) Turbo different on SD...has a wastegate too

hmmm...can't think of anything else right now...
