Kinda random but I was interested in the shaving aspect of it.  Do you have any idea how much something like that would cost, how much it benefits the M42 engine, etc?

I am also interested in the shaving process.  Do you have any pictures of the flywheel?  I am looking into the m20 flywheel swap...any idea how this compares?  Thanks!
