Cam reground
Trying to educate myself here.....there is often talks on lifter and cam hardness matching and being compatible. Question is....when getting a 'race' type reground cam, and removing a lot of material, what happens to the surface hardness? I would imagine that the original cast cams are surface hardened and a re-profiled cam will loose this surface hardness. Robert

Re: Cam reground
When they regrind a cam they take material off of the base circle and the end of the cam that pushes on the lifters is still hard. what is required is a longer valve to make up the difference.

Re: Cam reground
I'm back
Peter C....you had the cam "parkerized" after the fact of getting the re-ground L100 back from the folks doing this?? If so, who does this and what if you don't get this process done. Still clear as mud to me.....Robert |

Re: Cam reground
Parkerizing is just a surface treatment to assist in break-in of a new cam, it provides the ability to hold oil on the surface. If enough was ground from a lobe to remove any surface hardness it previously had then parkerizing would not provide that. Parkerizing looks a bit like black oxide with a silver tinge to it.
