difference between these two cams?

Moper not complicated to me. Just not experienced in such matters. And yes I did want to know approximately when or if the difference in duration would be felt compared to the difference in lift and not just seen on a dyno print out.

I did learn that lobe profile was also a characteristic to consider when comparing like durations. Not am I only here for advice but to learn more as well. I do appreciate all input.

Thank you
