Okay, think I have solved the water temp problem, with the help of posts above. I decided to chunk the electric fan and installed an engine mounted 7-Blade Radiator Cooling Fan that fits the 73-87 Chevy & GMC Truck equipped with a 305 or 350. I found I had about 1 and 1/2 inches clearence between the front of the 7 blade engine mounted fan and the rear of the radiator. However, I had to lower the radiator in it's housing by 2 and a quarter inches to keep the fan blades from biting into the bottem radiator hose ( required some slight fabrication and tapping new bolt holes in the radiator housing ). I then filled it with 1 gallon of antifreeze and the rest of the way with distilled water ( we have VERY hard tap water here ) and fired her up.
Result: Went from water temp of 220 to 240 to a water temp of 180 to 190 An average 40 degree drop in water temp. Waa-hooooo!!!
Thanks everyone for your ideas and posts, you guys are life savers.
