Cam Problem!

Yeah, I was thinking lobes..since that's what goes flat...lol. What is mentioned is mentioned because they are talking about the difference of pushrod oiling and shaft(thru the head) oiling, and certain mods..(I have that book too..comes in handy)

Mark, the cam cores havent changed. Beleive what you want, but the top engine builders didnt put it right back to the oil at first. The first complaints were lifters with not enough crown (difficult to measure, but feasable because of the selling of a bad production run from somewhere..cant recall which company), or a soft cam. I never heard of any damaged cam being rockwell tested for hardness, and being compared to "an old hard one..". Being that there were only a few makers of lifters, and a lot more companies selling them, I'd hypothesize that many of the bad batch did get into other sets, and that's what caused to supposed cam issue. I know the buyer of the bad batch did sell them again. They should have been destroyed. Also, 5 years ago, the "fast rate" cams were just coming out. It's these fast rates that mean it all has to be perfect, or the cam wont break in, it just breaks.
