Gto block casting number

I think I am looking at a 1965 GTO Engine but I want to make sure. The block cast number should be 9778789. However the numbers in the casting are one number short. It says 778789 without the nine. What gives? See pic.

That is a late '66 block, as evidenced by the June 24, 1966 date code. Almost the end of the production year. Didn't bother to look up the missing digit....
