cad 390 id help

Ok, I'm lost I got a 390 Cad engine supposedly out of a 60, my casting number is 1473267 when I look it up it states 63, but when I look up the stamped number prefix 07K I get a 60 390. So who am I to believe?
Thanks for your help.

 

The number on my 60 is just above the oil pan. The 63 is a whole different motor. Dist. in the front.

 

I've been looking at pictures of early 390 and the '63 390 and didn't even notice the location of the distributor, thanks for the tip. Mine is deffenitively a '60.
