<VV> Camshafts

Clark sez:
<snip>Craig Nicol says cams are soft when new and harden in use.  WRONG!
I have the Corvair cam drawings and they are flame hardened or induction
hardened, ground polished and coated with special compounds to reduce
friction.
So in effect they are made hard and slippery and are worn soft in use!

And I (Craig) reply - if this is true, why are failures common on new cams 
but not cams that have gone 25K?  Why won't GM warantee a cam unless there's a 
can of EOS (super protective moly oil suppliment) on the receipt? Why will a 
cam that survives the first 1000 miles go 200,000 miles?  Yes, GM takes great 
pains to harden the surface, but it gets even harder once it's broken in.
