Back in 68' I knew a guy who had a 66' 421 Grand Prix, It actually had a large diameter duall snorkel air cleaner!!! about ten years later at a pontiac parts counter I did see the actual diagram of the air cleaner in a parts counter book. There were part numbers and it said 66 grand prix tri-power. James

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.
