Quality Robert Shaw high flow 180Β° thermostat is modified to function properly at high RPM, high flow applications. High flow 180Β° thermostat. Notes : here are three bypass holes in the center area of this thermostat to allow water to circulate prior to the actual "opening".
Installed in a mild built 355 ci chevy, EX268H cam, 10:1 compression with aluminum heads and 2.02 intake valves and 1.60 exhaust valves, TBI, this thermostat would never allow my engine to warm up and the more I drove it the colder it got with temps reaching all the way down to 155 degrees. After this, I purchased the Robertshaw 180 without the holes and I had the same problem. After two tries with this style of thermostat, I went with a $6.50 Stant 45358 180f Superstat and could not be happier. Engine now warms up in just 5 minutes and maintains temp. Guess you don't always get what you pay for.
