If you're looking in Jegs, 689 prefix is just Jegs' number to signify a Melling product. On my 80-85 350 I just did, I used a Milodon street/stip pan #30901, with a Melling 10552 pump (which is stock pressure & 10% over stock volume). The only reason I went with 10% over volume, is I have solid lifters with the EDM holes in the face-otherwise would have went stock. The pickup depth to pan clearance was 3/8 or 7/16"-didn't have to mess with modifying anything.
