I don't mean to insult you. It just sounds too good to be true. I am also amazed that it isn't something that I have heard about before now. I lost 3 cams in 2 different engines due to lobe and lifter failure so I am skeptical about this. That is why when I went to a solid cam, I was really happy to learn of the oiling feature of the EDM lifters. Again, No Offense, I am still surprised at the idea of this.
