I wouldn't think that Parkerizing would offer a heck of a lot
of wear protection to a cam and it seems that it would be
scrubbed of in short order during brake-in as it doesn't
penetrate the surface to any depth the same as bluing.
Now Nitriding is a different story. Very informative article
there on comp cams. Nitriding has been use for machine tools
for ages, interesting to learn that it's being applied to
engine parts also. Nitriding also falls into the category of
heat treat.
That cams are not heat treated was a surprise to me Jerry. I
guess I was relying on articles from ASM Heat Treat Society's
magazine HTPro from 2013 dealing with commercial heat
treating methods for crankshaft and camshafts.
I'm looking forward to seeing what you can do with the 235
cams. To bad someone like comp cams can't be talked into
making a run of 216 camshafts. I'll bet you could get them
made in china, only problem is, like all Harbor Freight items,
they wouldn't work when you got them home.
