Quote: You are correct. Pinion angle is the relationship between the pinion centerline and the crank/transmission centerline.
Make the pinion parallel to the transmission as a base-line, then pivot the pinion downward 2-3 degrees. In other words, the resulting pinion angle will be 2-3 degrees under parallel (nose down) to the transmission centerline when the car is at rest.
BTW, there are some jokers around here who say I'm telling you to index the transmission angle relative to the pinion instead of the other way around.
I see a movie being made now of drdiff by the haters
