I got a smaller radiator that I was able to squeeze underneath the rad support. But I have seen people cut into the rad support and move the radiator forward. Either way will work and save you tons of headaches from worrying about coolant temp.

Theres actually a post here somewhere which shows exactly what was done. Carl H did it first. I did a variation of what he did...both work great.

Im using a big aluminum rad and what i did to fit the clutch fan was to cut the upper rad support back 1.5" and then drilled the holes 1" back for the bottom of the rad to drop in place. It took all but an hour to do. Super easy to do and if i do another RB this will be the first thing i would do. It will also makes it easier to put the engine and trans in since there will be more clearance for the crank pulley to drop past the rad support.
