Howdy to you all. 
I'm in a dilemma here. I'm running a Robertshaw (genuine stuff, not made in China) 160 degree thermostat on my 292, that is bored 0.060 over, has a Isky E-4 and a Autolite four barrel. 
People say I should replace it with a 180 degree thermostat, because 160 is "too cold".
Well, the car runs great, and my climate here is humid and hot, like let's say Florida (being there, and it was VERY familiar, hahaha) 
My engine almost never goes beyond 170 while driving on normal speed traffic, with a occasional 200 when stuck in traffic. 
What do you guys think?
