Overheating 360 new engine

And I know 72bluNblu is using a "Dakota" Control box but for those that want to do a Contour fan with simple wiring, well as simple as two relays goes, here is a wiring diagram the OP may check out.

You can add a toggle switch between the Ignition and pin 85 of the left relay to shut off the fans while running the 1/4 mile. Put a lit one in so you can see its off. OR, put a normally open push button on the shifter so when you push the button the fans cut off, finger off and fans come on.

I could draw one up adding a 3rd relay for AC control.

EDITED to add 50 amp blade fuze to drawing. Must have safetyContour Two Speed Relay.png.
