Hey Jerry, I like your idea! Has anyone just got rid of the fixed fan and used a modern radiator with electric, thermostat controlled fan(s)? I can lower my rpms significantly with my overdrive, but eliminating the fan on the highway would be the next level!
Sure...I did that and have never been happier. I have a 3 row aluminum radiator, a short shaft water pump/pulley, a Spal 2200 cfm fan and an aluminum shroud made by Old Air Products. When the thermostat turns the fan off, it just spins in the breeze. Engine is quieter, smoother (the old fans weren't balanced), and the water pump lasts longer without all the shaking and harmonic vibration. In Dallas, summer lasts about 300 days a year, traffic is slow at best, so you need something capable of cooling very well but traveling on the highway is a different thing. Good luck.
