200 seems pretty realistic. Even on our cars and DSM's, 195 is sometimes too much to ask.
The mistake many seem to make is using a lower than stock (160-degree for example), or poor thermostat. By having a thermostat that opens at just 160-degrees, or 170 or so, the purpose of having a thermostat in the first place is defeated. One of the main purposes of the thermostat is to control the flow of coolant through the radiator. By having a slower flow (i.e, thermostat half-open/closed), the radiator can better cool the fluid. I have always used an OEM 192 degree thermostat, and even in Florida weather have never run into coolant temps I was uncomfortable with, even with the stock, thin, DSM N/T style radiator.
Of course, the fan doesn't really apply in the warmer season, but wiring a fan that runs all the time is never good in the winter season, even in north Florida as I experienced this past season. The fan cooled too much in cooler temps and the coolant temps stayed well under 170-degrees much of the time, even after a long drive. The heat was borderline not quite working too well. With that, there is such thing as too cool as well, most noticeable in the winter of course.
Unless running an aftermarket/smaller radiator than stock, stock cooling systems were designed pretty well and get the job done overall.
And as I noted previously, I would not be concerned with anything under 220, especially after a good pull.
I will also note, our stock gauges suck. If there is doubt, always use an aftermarket gauge or a logger. The stock gauge over the halfway mark can never be good, as they are highly inaccurate.
