I presume you're talking about transport sync (not wordclock). If so, look at the manual for your 8 track - does it lock to MTC (MIDI TME CODE) and respond to MMC (MIDI MACINE CONTROL)? If so, you're good to go. Hook up MIDI cables between the DAW and the recorder and set the DAW as master and the 8 track as slave. If your 8 track doesn't use MMC & MTC, you're probably out of luck*.

*there are some other possibilities, but they are more complex and may involve external synchronizer/translator units (i.e. hardware boxes that cost $$)
