Puller electric fan with 4 core radiator?

Like 72blunblu, I run a Champion 3 row with the Ford Contour fan and a Dakota Digital controller. Engine is a built 340 pushing 425 HP in a 73 Sport. For clearance with the CVF Racing aluminum water pump pulley, I had to go to button top pulley screws. That gave me just enough clearance. No issues with interference or the engine cooling.
