Thanks for the pics Dragncar, my 73 casting is the same as yours. The identifying feature is the parting line from the casting and how the main/cam area is one piece.
I came across these pics below in a post from GRX back in 2006 that was about block differences. They are representative of my 71 block on the left and my 73 block on the right.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
