Bullcrap unless you can provide documented evidence that a gear drive transfers harmonics to the crank. Bullshit. You might convince me it goes the other way, from crank to cam. But not from the cam to the crank.
Do some research and see what actually uses a gear drive.
Edit: evidently, you've never seen what Fuel burning engines use to drive the cam. Or blown alcohol stuff. Or the 410 sprint car stuff that makes lap after lap after lap after lap with more lift than most people here run.
