thanks!
to bring this back to the discussion of “rubber rods” (a new term for me!) vs earlier SD rods vs 58-62 rods… it looks like the older stuff all the info is there; 1) what info is there to compare the (66+?)69-78 rods against the earlier ones? 2) so what might stop a person running an earlier engine with the later cast rods?

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.
