Engine/Trans angle?

[Z06vet]

I have been thru this many times in the last year. I still have not grasped it totally. The consensus seems to be- if the driveline is down X degrees, the pinion should be up X degrees. Basically if you were to draw a line thru the pinion angle & the driveline agle, they should be parallel. There should be some angle (either + or -) or the U joint will have a slight bind. Most research I have done suggests 2.5-3 degrees down on the trans is about as much angle that you should have. Lastly, the driveshaft should not slope upward from the trans to the rear end. I am no expert, as I am still working on my setup. Seems everyone has a different view on the subject. I'm sure other with more experience than I will chime in. Scott
