Interesting that those specs list it as "rocker arm" ratio. Since a "mean" (average) value is specified, the ratio must vary somewhat through the lift range.

It would Jack. As the lobe comes around the contact point on the "rocker" would be "sliding", changing the contact point and therefore the ratio.

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.
