Re: Almost done with restoration but shifting problem, and more.
From the post Radiator Flow, "If the fins have broken loose from the tubes it can empty in .1 second and still won't cool the water in it. Also, if it flows too fast it won't have time to cool the water in it anyway. I have an engine on my test stand that I ran yesterday with a standard open hose on the top. The engine in 10 minutes pushed enough water out the overflow and the temp got to 190 in 15 minutes. Today I installed one of the thermostat housings that was discussed here lately. The engine got to 160 in about 10 minutes and you could see the temp rise visually and it never got over 160 after running for 30 minutes. Sometimes fast flow is not good."
