So, a while back I got a set of Crane Gold rocker arms gently used. I started thinking that I wanted a new set of
shafts that were very hard as the rockers are not bushed. Soft aluminum running on a hard slick surface is ideal.
Mancini has these shafts that are advertised as being hardened AND chromed. MRE715 Racing Chromed Rocker
Shaft. Pulled the trigger. Got em. Took a file to them and NOT HARDENED AND NOT CHROMED!!
Called them up and said "WTF"? They said, Oh Well! What I probably wanted was the Stanke Motorsports shafts that are hardened.
They also sell them at Mancini for $189.99. I called Stanke Motorsports and asked them about their shafts and the guy explained that
they are "Melonited". Being a retired Machinist, I had never heard of that process but would do some homework and find out. I Googled
"Melonite" and found that it was a another company's "Nitriding" process. 426 Hemi Cranks are Nitrided to a depth of about 0.004. Very
hard, about 75RC. Dat's what I want! I went back to Mancini and bought them. They're supposed to come today, so I'll report back.
Funny thing is, niether Mancini or Stanke Motorsports leaves this vital information out of their description! If the guy at Stanke hadn't
told me about that process being used on those shafts, I would have never known.
