Radiator is ok and no leaks. Question to you that have Fontana installed what radiator do you have?

Forgott to mention that I have an oil cooler too,
temp in oilpan ca 90-100 celcius during high way speed but I have to run an electric fan now and then that is mounted behind the oil cooler
I have a 9.2 deck Fontana block with CHI 3V heads, CHI single plane air gap intake manifold and F.A.S.T XFI 2.0 fuel injection. It is a .060 bore with a 3.75 stroke, which comes out to 388 cubic inches. My engine actually was up to 200 degrees at 75 mph a few weeks ago on my way home from San Diego. The outside air temperature was about 110 degrees. At temperatures below 100 degrees the engine will operate at about 180 to 190 degrees, with a 180 degree thermostat. I have a remote thermostat housing, however I am running the water directly to the radiator and have the swirl tank on the low pressure side of the system. This method eliminates the restriction that the swirl tank causes. I have a three pass aluminum lay down radiator with two fans on the back that are shrouded. I also have a Laminova oil cooler which is on the outlet side of the radiator.
Cooling issues come down to low speed high temperatures being an air flow problem and high speed cooling issues being a water flow problem.
