the only difference I can discern is that the 67 manifolds are 3 bolt flanges on both sides vs. 3-2 on the 68-72. Text I've read on it says there's a change in the "runner design" between them but I can't see what's different. I have 67 manifolds on my 69 without a problem so I can't see why going the other way would be an issue.

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.
