Hughes cam?

And as Rusty started to say above, it depends on what YOU want out of YOUR engine, as to whether that advantage would even come into play. A daily driver, a mpg champ, a truck, (that's used at one at least) probably won't get into high enough RPMs for such an aggressive cam to the point where you'd see the difference in a "regular" cam design, or one where the lobes are ground to work better with a bigger lifter.
But then again the setup is probably pretty identical, as far as doing the actual cam grinding operation, and the time spent doing the grind, probably is pretty close to the same as " most of" the work they would do, so I can't see getting what you would want out if them, being any more cost than their"regular" work .
Maybe you might see an advantage on another sense, as being that they probably don't get asked for such a profile very often, meaning that if it calls for any different tooling than the normal stuff, could it be that such a cam could be kept on tighter tolerance because of being cut with tooling used less often and therefore less "worn out"?
