[csx4017]

The CSX4000/6000 is built with the two pusher fans ( replicates 1965 ). I had a mounting bolt fail ( fatigue failure ) and almost took out the radiator. I have run with and without ( 105 degree ambient ) and concluded they add nothing. They are setting in the garage for the next owner. Rick is right again about the twin pushers looking cool but, my 16 inch puller is all my 427SR needs. Angling of the radiator allows for more square inches of surface area while providing hood clearance. Bottom line for me is that I rarely get above 90 degrees C. in stop and go traffic. I think Rick has checked all the boxes for you.
