Default 160 Thermo or 180?

Installed a 160F in the LS1 -Z28, but its so hot here in Fla cars will always exceed that temp even with fan switch, so thinking of a 180 for the Vette. Opinions?. Got a Diablo programmer on the way so will turn on fans earlier along with fine tuning factory settings. Just installed a 2 filter system and it looks and feels great, drilled holes behind ZO6 screens.

Just got to get this red slug to move out as well as the old Z28 which was I guess just a naturally fast car! with minor mods. http://home.att.net/~sy13/corvetteogc5.html
Thanks for any other cooling down tips and suggestions.
Tom

The 160 will keep you at 176-178 at highway speeds. On the "cold" Miami winter nights I've seen it hit 160's. The 160 thermo is good here-but up north I'd go with a 172...

:iagree:

And oil temperatures are still around 192*-198*

I agree with both statements. In almost any ambient temp, my coolant runs 178-180, and oil 198-200 using the 160* thermostat. So I run it year-round. On the track, my oil temps hit the 280s (I have, but haven't yet installed, a DRM oil cooler). But even on the track, my coolant temps stay below 220. I'd credit that to a pretty good stock radiator.
