Probably would move more air, it is a more modern and quieter fan blade design also.

I don't know how you would adapt it to the direct driven D24 fan hub though, unless you added the viscous clutch also. The 740 style fan has wider spaced mounting points for attaching to the outer perimeter of the viscous clutch unit and wouldn't bolt directly onto the skinny hub spacer from the D24.

But you do raise a good point: maybe swapping in the complete 700 series D24T viscous fan setup would actually improve cooling capability, not because of the viscous clutch drive, but because of the different fan blade section itself. I hadn't thought of that.

Only one way to find out -- try it and let us know! If you have trouble finding a D24T fan setup, the fan blade is identical to what is used on any gasser 4cyl 240 or 740 so you could harvest one of those from a JY also.
