My other engines are 12.0(Pontiac w/RA II heads), 10.2(Pontiac), 9.9(Buick) and a stock '71 455HO engine. No pinging on any of them. I do run 100+ octane in the 12.0. So, this is a little higher but nothing like the 12.0. I do have ready access to 93 here in Texas.

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.
