i did the whole f-body aluminum radiator and ramchargers dual-fan swap at the same time. I dont know how much of the improvement in cooling came from the rad and how much from the fan, but its like night and day difference. Before I was always running above 200, more in the florida summer with the AC going. Now, no matter the outisde temps, and with AC blastin, it never gets much above 160. Wiring in the fans isnt toooo tricky, and you can wire up the ECM to controlt he fans, if you convert to the later 86/87 style ECM.
