Idle shake
Trained ear, yeah you can hear the faint loap at idle.
Compared to a stock cam, the difference is night and day.
Most people over cam their engines when building them, so they don't idle well. They start making power at 1500-2000 rpm to 5000-6000 rpm... not much at idle.
Stock cams start making power right away, more low end torque.
0 rpm to 4500 rpm.
