Hello FOW, I am interested in ur Flex Fan. I have a fac flex fan and stock radiator in my Comet 302 and thinkin abt elec and alum. radiator. My car runs cool enough in motion but if I drive freeway and then slow to crawl traffic it may go to 210+ w/ I believe 160 stat; not sure on the stat cuz owned the car 6 mos and have'nt got around to checking. My temp gauge in 40 -60 won't go over 150--160 moving. Anyway don't really want to go to elec fan unless I have to. To make a long story short what fan were u using prior to the swap and was there enough improvement to justify the change. Appreciate any advise. Thanks. Everett
