Need help Identifying 289 Block with Screw in Freeze plugs

[daltondavid]

I got this block today. It says 289 in the lifter valley and has 2 Bolt mains. 4 of the main Bolts are tapped I imagine for a Windage tray. The screw in Freeze plugs are reminiscent of the Boss 302 and 427. I have never seen a 289 with screw in freeze plugs. Does anyone know anything about this! All input appreciated.

Yes windage tray.
Probably an owner "upgrade" on the core plugs - https://fortesparts.com/product/ford-performance-parts-threaded-freeze-plug-kits/

Exactly what was said above. Not uncommon but also not very common.

     Back in the day, for race effort 289/302's, it was popular to convert the core plugs for screw-in type, and we did many of them; and this included the addition of the BOSS 302 windage tray also.
