Standard or Reverse Rotation Fan 351C

[GrillMaster]

I have a 351C that spins clockwise if you look at it from the front of the motor. Do I need a standard or reverse rotation fixed fan?

Thanks

Water pump spins the same direction as the crankshaft (all V-belt setup and serpentine with grooved water pump pulley) is standard rotation

Water pump spins opposite direction of crankshaft (most serpentine belts, water pump rides on backside of the belt) is reverse rotation.
