Drag cars often turn RPMs into the 8k range and run steel driveshafts, i would probally be more interested in the 0 degree at the tailshaft of the trans. Are you saying that the driveshaft and yoke are perfectly inline? as in 0 degree?
No, the trans centerline is at "0" and the pinion is pointing nose down "2" degrees. The rear end is below the transmission centerline, so not sure exactly how much angle the driveshaft leaves the transmission at.
