Tom,
Yes, most engine dynos still use the SAE J607. The car manufacture in the early '70s changed SAE J1349. I believe some chassis dynos also use SAE J1349.

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.
