Usually a fan blade is designed with a leading edge and a trailing edge for many aerodynamic reasons. Check the fan in your house or an aircraft propeller. Some fans that were used on a fluid clutch had the letters "RAD" of one side, for instance.

55 birds used a chromed 3 blade fan when the car was ordered with the engine dress up option.  Because of embrittlement due to the chroming process, the fans came apart. The fix was a reinforcement plate.

Go to Amazon or Harbor Freight and buy a cheap infrared thermometer, and find out what temp you’re really running. Best cheap tool you can buy for checking temperature. At the temp sender, the thermostat, the radiator top and bottom.

If you need more cooling and it will fit, here’s a link to an old post where Greenbird talks about the clutch fan. When I did the radiator/ fan set up I didn’t have room because of how the supercharger drive set up. But given my choice, I’d use a good thermal clutch and a big fan/shroud combo first.
