Where does that leave you? We are judged by our actions, not by our words. So you bring absolutely NOTHING to the table but what you can google up with your "trolling" and I'm NOT the first bit interested in anything you have to offer, camshaft or anything else related to this hobby.....FWIW....

Yes, right at 300, maybe slightly less at 600 lift

This fact also shows how important Intake head flow is in that lift range even if max lift air flow numbers need to be comprised to have them!

I think you're getting your posts mixed up. My old 464 or the new 517 don't/didn't have .200 durations of 140/160.
