Re: 81 K20 Thermostate 160
Standard replacement should be fine but I would run at least a 180 deg stat.
The engine wears more if you run it to cold. I'm dating myself here but Smokey Yunick did a study or article years ago showing the different wear characteristics on the diff stats. The only advantage to using a cooler stat is cooler denser air for slightly more power. My .02 cents. |

I would also run a 180 T-stat. I prefer the Robertshaw high flow “edge seal” thermostats.
