Hey Plainview…
Thank you! I had no flipp’n idea what cam timing is. ![Distrubed :disturbed:](https://board.marlincrawler.com/Smileys/marlin/disturbed.gif)
I clipped this from Crower’s website: https://www.crower.com/camshafts.html?cat=1065
Can you please tell me what the ICL is for those “published” specs?

Surely you know enough to know it can't be determined from just that info. Why Crower chooses not to publish their lobe positions or opening/closing specs is something you'd have to ask them. If I was considering one of their cams I'd ask before purchasing.
As for why LCE grinds advance into their cams while other manufacturers don't, that's a great question. When it comes to a company like Comp, I'm always skeptical that they've taken the time over the years to actually test their cams. I'm not a fan of off the shelf Comp grinds for Pontiacs because they're very generic and aren't really suited to making best power in those engines and it looks like they may have taken a similar approach with the 22R/E cams. LCE on the other hand has been doing Toyotas for years and years, I'd trust their expertise over Comp's any day. But then there's TRD who you'd think would be the ultimate source of knowledge about these engines...
What does your simulator say?
