No, the mag fan was introduced because it was cheaper.   I'd wager 
the '62-63 fan is better at moving air than the mag fan although it 
remains much heavier and more expensive to produce.


That mag fan is a simple casting that has NO attention paid to 
aerodynamics or efficient air flow.  The only thing it does is beat 
out a more efficient fan in manufacturing costs and less weight, 
which means belts will stay on better, both factors more important to 
GM...  efficient cooling is a lesser matter when money is concerned, 
when the mag fan would be "good enough".

Well...  we see today that in certain applications it's NOT enough.


I would really like to see some modern test specs on Corvair cooling 
fans.   I mean *Modern* test specs and not the specs that GM drifted 
down through channels.
