My post came directly from the 1969 Pontiac parts book.

Thatīs odd, none of my books, 1970 Pontiac Master Parts Catalog or Delco Parts&Service manual #9 shows #63 jets for any 1966 Tri-Power center carb?

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.
