66-427 marking is meaningless...... |

This marking appears on 428, 410, 352's and 390's. It means nothing. A real 427 will have at least a 4.23" bore and crossbolted main caps on #2,3 and 4 main journals.
The ribs on the side of any FE block mean it was made after 1970 approximately. These ribs appear on 360 and 390's plus 428 industrial blocks too.
