Does anyone know the measurement of the distance between the center of the piston pin and the top of the piston? I need two measurements if possible both for flat top pistons. I need one for a 428 and the other for a 455. Any help would be appreciated.
Thanks, Unchained

Approx. 1.615" for the 428 and 1.490" for the 455 if my maths are right.

Keith Black lists the compression height for their pontiac pistons here.
Feidlerh is correct. The IQ and life expectancy of the average American just passed each other going in opposite directions.

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.
