Joel,
You've got it "inside out". 
The Delrin (plastic) fan was to be introduced on the 1962  Corvairs, but the 
outgassing of the battery caused Chev to replace the delrin fan with the 16 
vane metal fan. The magnesium fan was introduced in 1964 to inprove fanbelt life 
and had nothing at all to do with the outgassing problem.
