Gary,
I think coatings were recently mentioned in regards to firearms.
Perhaps when Robar closed up shop in September(?)
I have a couple of pistols done in Np3....
And had various engine components done on my race bikes back in the day by Calico up in Maine.
Piston skirts and crowns mostly, there are no valves, cams, springs or wristpin bushings in two strokes.
But we were definitely pushing piston speeds to fearsome levels.
Seizures were going to happen if your mix and jetting were not spot on.
Jim,
Lil'Red is a '87 F250 HD, 4.10's, 1356 4x4, Zf-5, 3G, PMGR, Saginaw PS, desmogged with a Holley 80508 and Performer intake.
Too much other stuff to mention.
