how much electric fan cfm??

i partialy agree with Krabysniper but another thing to look for with a stock type fan is that you realy need a shroud on it, it makes a whole world of diference!
sure electric fans work i have a 16" mrgasket fan and a radiator taken from a 4cylinder ford scorpio and it keeps my hardblock filled 340 cool even at standstill cruise nights in warm summerwheater! (record so far is 8 hours without any stop for cooling, in fact it has never overheated beacuse of a to small cooling system)
