Ahhh ... engine blueprinting. Seems to me such variances can be attributed to quality control at the factory. It would be nice if a machinist calibrated the equipment for each individual block. But that would be too time consuming & expensive when doing large production numbers. This is why no one single number can be tied down since no two are exactly alike.

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.
