If he'll let you, you can try to see the casting number on the back of the block. It'll be right behind the head on the driver side between the head and the bellhousing. I don't know the 400 casting numbers right off hand, you'll just have to look them up online, or ask others. Its easiest to see the casting number with the valve cover off.

Waiting to build my 400.
