Purple Cam Design Question

In addition, didn't some folk here work around these cams only to find out the Lunati cams have a larger duration @ .050 than the MoPar cams?

Yes, that's true.....BUT only since ....I forget what his name is that ran Ultradyne went to work for Lunasty. That's what the Voodoo cams are essentially.....they are very close to some of the old Ultradyne stuff. Good grinds, too. But Ultradyne always ground on the .904 lifter reference......even before MP finally got their heads outta their back sides.
