is a t-stat worth it?
It appears to be the general consensus that the stock one is fine and just reprogramming the fans to kick in earlier is the easy option.
while a cooler engine may be good, one running too cool is also un-efficent. It's a balancing trick and personally I'm quite happy to lean on GM research.
Also probably not really an issue in FL but a lower temp thermo may also make the heater appear less efficent.
A larger core radiator and/or oil cooler are the best bets for improving the engine from a temperature aspect.
