As a rule, I prefer a 18" stainless flex fan, usually the 10,000 rpm rating gets you a pretty good one. I do use that plastic Flex-a-lite on lots of stuff, but S10s wind up with too little clearance. I trashed a radiator with one one time, at 7000 it flexes just a bit too much. I made an aluminum stiffener for it, (went in front, kept the blades from flexing forward too much), ran it for a while like that, then it lost a blade, stuck this little chincy aluminum one on it and it ran cool with that one so I left it. I am gonna stick a Taurus fan in front of my 4.3 and see how I like it though, (testing for the fan control unit ya know,

), if it works out well I may keep it in there for the V8 swap. The 4.3 needs all the help it can get, but I don't want to sink any real money in motor mods.
