160-degree thermostat too cold?

Seems like I remember hearing that companies that re-flash auto ECMs for more performance, recommend a cooler thermostat, probably because of the more aggressive advance curve. This might be considered a "crutch" but I think it may help, if only a little......and like was stated, only if the cooling system if stout enough to bring down the coolant temp to 160, which is a bit doubtful actually, since it's a small block cooling system trying to cool big cubic inches.

I think it's worth a try, if only to help a little bit, plus it's interesting to see if it does.
