I have finished my toyota project but am having one last problem. I have a 1980 toyota with tbi 350 with a th350 trans and dual toy t- cases. the radiator I have is a howe two row. core size is 23" wide and 19 " tall. It will not get hot right away but the longer it runs the hotter it gets. I have changed the thermostat (180) installed a high flow pump. the only thing that is different than when this engine was in the blazer is I caped off the line that went to the heater core. Running a 6 blade flex fan. I have also tried a differint gage, no change. Is this just not enough radiator to cool this thing. It seems bigger than the one I ran I my jeep years ago with a v8. I was hoping maybe you cooling system buffs could give me an idea.
