Running a brass/copper radiator, cannot tell brand. I believe it was not the original. It has tranny cooler in bottom. I have an aftermarket chrome water pump, again no brand or model #. (I bought this car and it had been in storage at least 5 years or more, old build) As I said elec. fan thermostat in bottom of radiator tank.
Yes the hood is on, but not stock it is louvered top and sides extensively, but still could cause a flow problem. Good suggestion, I'll try it without the hood and see what happens.
