Oh, I've gone round and round on my tuning and temps. I have it dialed in well now. I was running 210* at 3,000 RPM before. I have at least 2 full, long threads on the subject.
Short story: replaced restrictive electric fan with Extreme Duty Hayden mechanical fan, spring modified, 18.5" blade fan. NEVER runs over 180* at low speeds or idle. No shroud necessary. Tuning is really dialed in nicely. Starts right up, runs great all over, eliminated highway speed 'trailer hitch surge' thing, no pinging, etc. 16* @ idle, MECHICAL advance 24 @ 1500 RPM 31 @ 2000 32 @ 2500 36 @ 3000 (all in) Plus 10* vacuum advance using modified unit with .12" travel per Cliff which worked like a charm. (car hated ported vacuum advance). Runs clean, idles smoothly, doesn't smell. If memory services, I went with P/N #1850/AR20 advance can. I'd have to double check my notes on that one. It opens with 4-6" of vacuum. I'm good.

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.
