Low speed torque and driveability ?

I don't actually know but have "read" long duration cams have very poor cylinder filling and mixing, are
inefficient and make very little power at lo rpm.

I've always heard and thought the same but now questioning it.

That broken idle that most guys love is actually raw gas burning and exploding in the exhaust system.
Maybe it's not the torque number but just poor performance created by a long duration cam at lo rpm.

Idk but I'm thinking overlap is probably the main culprit not necessarily loss of torque cause if an engine doesn't like to idle at low rpms it probably don't like to drive at those rpms too. I'm thinking if there's lesser torque is more of a correlation than causation. But I could be wrong still trying to work it out.
