My truck has been running a little on the warm side 200-220,with standard t-stat(192 degree not robert shaw). I removed the stat and its running too cold now(160). My ? is when I get my robert shaw t-stat which one should I get 180,192? I live in FLORIDA.

 

I've been searching the net and bronco grave yard is out of stock on their robert shaw (333-180 t-stat), I see flowcooler only offers the 192 degree t-stat. I was thinking that running the 180 would be better to run here in florida instead of the 192 degree. anyone with some thoughts on this choice?, or just run the 192 degree because thats what the book calls for on the 351m-400 motors?
