I can only use a pusher fan as there is no room for pullers or blades on the water pump.I used to have a dual fan ssetup out of a 90's firebird.It was borderline sitting in traffic and finally centrifically exploded after a pass over 140 MPH.Thank the cooling gods it didn't take out the rad!
I then went with a single Spal 16 inch fan.I do not have A/C or any shroud and it never goes over 190*,normally sits at 180/185*.The fan cost $135 and blows better than ANY women you ever had

545 inch 9:1 cr.,,,, Might get above 190 waiting on line to get into a hangout. Works for me!So a single spal fan mounted as a pusher is keeping that monster cool?
Is that with the A/C on?? LOLThat big,beautiful roots blower acts as a great heat-sink to keep temperatures in check. My buddy has a 1937 Ford with a roots blown 383 small block. The grill in those cars is about 18" wide. 2 Spal 11" fans mounted vertically as pushers (no room on engine side, like Hemi) keeps it right at 180*, even here in hot, sunny California.

The gray box on my shroud is and aftermarket controller that turns them on low at 180 and high at 190, or whatever preset I want to put in and has a/c override to kick on hi when a/c is turned on. Not using the stock resistor setup.When I mentioned 2-speed fan control, I was referring to the gray box on the lower left of the shroud. It has a resistive wire section to run the fans slower to reduce noise. I control the fans with the EFI which senses the engine temp. Before the EFI, I used the Dikota Digital fan controller that could read the stock sending unit in parallel with the dash gauge (The IVR was converted to electronic long ago.)

I got it from Entropy Radiator. It's all 10 gauge wire and Delphi weather pac connectors. Waterproof "good" relays. He has a lifetime warranty on the wiring harness. I'm still struggling to get it started so I won't know how it works until I do.That's cool, where did the controller come from? I thought it was the stock setup, except for the gray color. The stock resistive block one on my fan was black.
