[Katrina/10]

I put a V8 in my 51 years ago and ran a solid mounted flex fan just like yours. It turned out the same way, with the bottom fan blades below the radiator. I had no fan shroud at all. It never caused a problem with overheating, although I didn't really like the way it looked. I left it that way until I added air conditioning, then went to an electric fan to get better air flow through the condenser while moving slow.
