I measured my driveshaft on my truck YEARS ago based upon info from Inland Empire Driveline Service which was supposedly the EXPERT on drivelines.
They say that the "standard" for engine angle is 3 degrees below level. So I would start with that. It also makes sense to do that because it's pointing more directly at the pinion that having it flat would (unless you have the front of the motor seriously low).
Next Inland says to have the pinion point 3 degrees above level. This way the pinion and the tranny shaft are parallel. Not necessarily on the same plane, but parallel.
Next they say to draw an imaginary line between the center line of your tranny shaft and the center of the pinion.
Then measure the angle between your pinion / tranny and that line. This last angle should be less than 5 degrees.
Basically they say that less than 5 degrees ensures maximum life for your u-joints.
I'm not sure that my current setup follows these rules to a "t" but it's pretty close!!
