Cam coatings ???

When the oil additives changed did the cam manufacturers change the coatings they applied to the lobes or was ther really nothing new to be done in this area ?

I think more are going to a Parkerized finish that does a much better job of holding oil on surface during break in.
Didn't Comp announce a new finish a few months back? I haven't heard much about it...

I think Comp offers nitride treatment for cams now.

Is nitriding becoming mainstream now or is only on custom orders

Comp offers nitriding as an extra cost option, so I wouldn't say it was mainstrean.
