I have a 2 bolt 67 400 that is .060 over. I would like to get is sonic checked just out of curiosity. But I do not think anyone does it around here.

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.
