    I would say a fixed blade fan with as much pitch and blades as possible. Look at factory fans on A/C equipped cars. If you have the room, clutch type fans are plentiful.

    I agree with Gasser, most pickup truck have more blades.

    I read a article in one of the BIG mags a few years ago that tested the flow and cooling ability of fans. Fixed Flex Electric none of them could come close to the five blade clutch fan.
     

  5. I always sought out solid Caddy fans for my stock cars. Which was a double-edged sword if the radiator got pushed into one. I've seen aftermarket ones similar to those with 6 blades or so.

    Now that's a great fan above.
    You can use the best fan ever,but if ya need it to work right,it needs a good shroud...........

    We have used Flexalite plastic fans to fix cooling issues on a lot of different cars...... They're inexpensive and they work.
     
  10. I don't have a shroud on any of my cars and can sit in traffic all day long and not run hot! HRP

    I don't know if this one is anywhere near the best but it will suck a cat through the radiator if he gets too close. it came off a Dodge Van that I had.
