Although my cooling issue was different. 205-210* at highway speed. Lower temps at lower speeds. Ambient temp approx 80-90*. Factory shroud, 3 core rad, 7 blade fixed fan. Fan is 1/2 in and 1/2 out of the shroud. New "stock style " 8 vane water pump. 190 tstat.
My timing cover had another coolant leak.(twice in 2 years now).
R n I'd everything. Replaced gaskets, fresh coolant 50-50 mix. New tstat 160*.
Dropped my engine temps a minimum of 30*. I now run AT MOST 175*.
I've read lots on flow, 6 vane vs 8 vane, different temp tstats etc etc. I know I'm babbling but in my situation a tstat fixed it. Your situation might be different.....
Good luck
