Put a Champion 526 radiator in a 71 swinger?

I'm not sure my hood will close if I install this radiator in the stock location replacing the /6 radiator. The stock radiator is about 19 inches to the top of the cap (rough measurement while in the car). Has anyone tried installing the 2374 Champion or the American eagle 2374? Its listed for a 70 charger/challenger. It would be awesome if like 15 people replied that both radiators fit perfect (with pics to show how well it worked out) LOL. its never quite that easy. Big HP claims on Monster Cooling for the American Eagle. Is 1"tubes that much more efficient than 3/4"? I will be trying to cool close to 400hp 11:1 small block. Any help is appreciated. Not sure if I'm supposed to be starting a "thread" or am posting this correctly. Set me straight if not.
