Turning torque for engine

Ok, found your other post and went through it. I saw that you thought you had a spring in the lower hose, the. determine did you didn’t. But I couldn’t find where you said you had put one in. Have you? My suggestion is, divide and conquers. Is it incorrect coolant flow or air flow or abnormal heat. Let’s eliminate air flow. Remove the schrouds and electric fans. Put one of those big electric squirrel cage fans on high right in front of the radiator and run the the car. You KNOW that will put out enough airflow. If the car doesn’t overheat. You have an airflow issue. If it still overheats. We move on to coolant flow. You can have too much or too little. Something I couldn’t find you answer to. Which freeze plug and did you look in the hole? Could this block have a short fill of hard block? You could remove the block drain and see If Water comes out, you may need to poke around in the hole to clear the casting sand. If after probing it you can’t get the hole clear. It might be half filled. I couldn’t find anything about the history of the block.
