The distance depends on if you are running a shroud or not. You want the fan to be about half in and half out of your shroud.

to answer your question - 1 inch min. between the fan and the radiator.

I believe I'd leave more like 3 inches just in case something got squashed, like your
front end. but shrouding and centering in shroud are important.

what is the air temp that you are running under right now that could be part of the reason running in the shop at 50 is alot different then running 6000 rpm in 85+ deg in the summer a good shroud is very important to a good working cooling system

The distance doesn`t realy matter. What matters is that you have a good shroud that is sealed up and that your fan is half in the shroud and half out..

With a shroud the distance isnt as important but if you are not running a shroud keeping the fan close to the radiator insures that the air is pulled through the radiator itself and not from around the radiator. A shroud will help pull more air across every part of the radiator not just the part in front of the fan..
