I don't have an issue with the Purple cams. Though like ramcharger said, the modern designs are very very good and unless there is a need, not want, need, to run a single pattern cam, the Purple cam could be a good choice.
Could be.
Your 400+ cube engine is doing what? What do you want out of it? What heads?
The 292 comes in @ 248 @ .050. Use this to compare it against other cams advertised duration and duration @ .050. I've noticed there more stout than most cams but not as aggressive as race cams that are streetable in style.
Of course, full race cams are a different story.
