What is the desired maximum operating temperature I should see? 1967 Camaro, 468 BB, shrouded clutch fan, aux. pusher fan. I'm seeing about 195-200 degrees after driving the car around for about 45 minutes. I changed the coolant and installed a 195 deg. thermostat. I've heard removing the thermostat entirely in the summer. I going to a car show tomorrow, about a one hour drive. Motor turns about 3000 rpm at 55 mph. Thanks!!
