flex-a-lite mechanical fan ?

well i'm getting ready to do a radiator (3 core) and was thinking about replacing the stock mechanical fan with a flexible flex-a-lite fan . has anyone used one ? what size do you get ? did'nt know if I fit a bigger than stock one in there.not really looking to upgrade to a electic right now , was just thinking about one of these fans becouse you can pick them up for around 50 bucks. thanks

See my site as it has all the information you are after including facts like needing a minimum of 2500 CFM plus the A/C fan.
The last write up on using a Taurus fan I feel is the best setup I have had.
