I have a pusher fan mounted behind the grille on my truck, cooling my 261. I have it stood off from the radiator about 1/2 inch mounted by parallel bars bolted to the frame that holds the radiator. It works great, and its not visible from outside or under the hood unless you really look up under the grill bars. It keeps the truck cool just fine in 100+ degree temperatures. Mine draws about 20 amps though. I use a thermostat so it doesn't run all the time.
