When I bought my 69' Catalina, it had the 2 barrel, 8:1 Compression motor. Basically the weakest one you could pick from. Since then I've rebuilt it and want to compare all the components that I have on now to the stock ones. I want to know what duration the stock cam was in this engine and what the valve lift numbers are. If anyone could provide me with the information I'd appreciate it.
Thanks

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.
