I still don't recommend the 160F stat... they are just too cool for the modern engine.
The various metals are designed to work at very specific temp ranges, and those are between 195F-220F. This is the type of temps the computer is expecting.

And that is exactly the range my gauges show my car to be running at.

I am not sure I understand what metals you are refering to, do you mean the use of allum. and iron?

If one is not reprogramming the fans they both will be operating at about the same temp. when warmed up. The gain I could see using a 160* is if you are trying to be in a certain temp. range w/fan programming, and ambient temps. are relatively warm (above 60ish fahrenheit.).
In south Florida you can go with a 160 tstat. My operating temp are just under 190 always. Many vettes down here don't uses a thermostat at all. I use a AutoZone 160 and it works great. I usually run 185 all year around with a big mouth air dam. I drive 1800 miles a month.

Exactly the same temps it would run with a 180° thermostat. The only thing the 160° stat does for you is lengthen the warm up time and add, slightly, to the wear and tear of the engine.

Anyone condoning a 180 stat on a TPI should be condoning a 160 on a LT1.
Anyone insisting on a stock 180 stat on a LT1 should be insisting on a stock 195 stat on an TPI.
I understand the logic. But where does the advocate for a 160° stat in an L98, fit with the GEN II crowd?
I have a 160* in mine. I haven't fired up the engine yet, so I cant say for sure. Where I live, we have extremes in both high, and low temps. I may have to use a 180*, but at the time I was installing it, 160* was all they had. All I can do is wait, and see. I've got to get the overdrive working today. Always plenty to do...
EDIT: If the car seems to run near the 160 mark, I believe it would be wanting to switch back, and forth, between open, and closed lope. Correct me if I am wrong...

The thermostat doesn't determine the engine's operating temp. It only defines the minimum operating temp, not the norm or the max. Once the stat is open, it has no further control, it's out of the picture. It won't run any cooler with a 160° stat than with a 180° stat regardless of hot the weather gets.

RACE ON!!!
Exactly, that is what I am counting on. I was just thinking about a cold day, and cruising on the open road... I've got my cooling system up to par now, but like I said still haven't fired it to see the real world effects my sweat equity has bought me...

Both LT1 and L98 are in closed loop well before the 160 opens. LT1 has temperature settings in the computer that prevent closed loop before a set temperature is reached (~150) and L98s will be in closed loop at about ~140, which is where mine goes in. Later L98s may also have a temperature setting in the computer, but I guarantee its lower than 160.
Those who will tell you that you run in open loop all the time dont know what they are talking about. And all the engine timers all expire within about 2 minutes.
