It's not odd, it's factory. The factory part number for that plug is 577646, and it was also used on the 61-63 394s in addition to all 64-65 Olds V8s. Unfortunately I suspect you'll be hard pressed to find an NOS one.

Use the ratchet without the extension. My experience is that an extension will sometimes slip in the recessed plug. There's actually a special 8 point bit tool made for these plugs if you can find one.
Grp 1.453 p/n 577646 oil pan drain plug, 61-63 exc F85, 64-65 all V8. It cost all of 46 cents in Nov 1973 parts book. So, if you can't find one NOS, it can come from another 61-65 engine.
