Purple Cam Design Question

SpeedThrills said

When Mopar designed the Purple cams, did they take advantage of the larger diameter lifters?
I've read on here that they are an out of date design. What makes them old? I have a 292-509 that was in the 360 I bought and plan on using it until I build a 408.

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.
