I have one I can measure for you tonight. Tell me how you would like me to take a measurement so we can compare "apples to apples".

Just measure the length of the divider wall (common wall).

My dividers have the leading edge modified some, how much from as cast I have no idea. I measured about half way up the side. And the face at the port openings has been milled a touch.
ports 1/3- about 5 1/4 inches long ports 2/4- about 6 1/4 inches long ports 6/8- about 5 1/4 inches long ports 5/7- about 6 1/4 inches long |

But you get slightly different numbers depending on which side of the runner you measure

Just measured my manifold, it is unmodified in any way. Measurements were taken in the middle allowing the tape measure to follow the curve of the center divider.

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.
