Both of my ‘72 481988s are 10.225-10.230; my ‘59 389 block is 10.245-10.250. Seems like PMD let the spec drop over time, Tom.

About Us

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.
