mixed info on setting pinion angle?

When you accelerate the pinion will rise. This is a known fact. The drive train is happy when the engine drive line angle is equal to the pinion angle (under acceleration). So if your drive line (trans angle) is down 3 degrees your pinion angle should be down 2 to 3 degrees (down) more than the drive line angle so that when you accelerate they become aligned (equal). When you accelerate the pinion will rise (2 to3 degrees) depending on your springs so you always have to set your pinion angle lower than your trans angle.
