Less stress on internal parts, with more RPM. I don't think we were at the limit of power with the 4.5 stroke yet, but we were out of RPM. The majority of current big power power boosted Pontiac are in the 480 to 500cid range.

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.
