Gotta agree with Chip and 1967Tempest.
I'm running on 87 octane with my 400 4bbl 4speed and 3.55s, with a CR of 9.5 to 1. No ping or any other problem..... well a small overheating issue tho but that's all and it's not the engine's fault per say. It's that water pump problem that a lot of us are having. Tho it stays cool so far with a 160 thermostat.

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.
