Nice vid Shannon. Sounded like Will Hanna's voice on the camera.

I phase the rotor on our belt drive distributor on the car all of the time, we spend all but the first 1/2 second of our run at 6 degrees BTDC (and there is a ton of cylinder pressure then) so I favor the rotor/cap overlap heavily to that part of the run (verses where it idles at 25 degrees and there is very little cylinder pressure).
