440 engine was in a chassis car last year with external oiling, putting it in my Duster for this year with standard pan and pickup. Went to remove the pipe plug and found it was real tight. Put a good 5/16 hex bit into it and tugged hard with an 18" breaker bar, hex socket stripped out.

Motor is all together and I'm thinking of ways to get this plug out. Maybe stuff the insides with rags and drill it out?
