Technically, "pinion angle" is relative to the transmission centerline, not to the ground or to the driveshaft.
Setting pinion angle is easy for your application. Make the pinion parallel to the transmission as a base-line, then roll the pinion downward 2 degrees. This downward angle is referred to as "2 degree negative" pinion angle.
Most of the time in stock bodied cars, a 2 degree negative pinion angle will still point upward, relative to the ground.
but Cass you know you can't teach these old dogs new tricks

Your right, us old dogs know when we are right, why change what you think because the majority thinks your wrong

Go get em Cab.We been doing it wrong for so many years that it seems to work out right for us.That this is relative to that or isn't to this is a contridiction by their own defination.The best place to find all things relative or all relatives in general is at a West Virgina wedding.

yea these guys don't know what they are doing either they only have some of the quickest and fastest cars on the planet.
Pinion Angle Tired of breaking cases and drive shafts? There are many books that misled you on setting the pinion angle. For Drag Racing this is simple. You are trying to set the pinion angle to be parallel with the centerline of the engine & transmission on hard acceleration. To achieve this you must first figure out the parallel setting of the rear end to correspond to the angle of the engine & transmission, then add the proper amount of pinion angle. Add 1 deg. for 4-Link vehicles, 2 to 3 deg. for ladder-bar vehicles. Place stands under suspension to duplicate vehicle at ride height. Caution do not remove drive shaft without securing vehicle first. Take measurement with drive shaft removed.

I would like to put a camera under my car and see what changes it goes thrugh as my car makes a run. I run 10* nose down in relation to the drive shaft, but if you look at my car in the photo you can see the spring allmost hitting the ground on launch . I ran the car with from 5* to 10* noes down in relation to the drive shaft for a lot of years. I have an extra 1/2 leaf on top the spring in the front section of the spring and a clamp at every leaf.
I have thought about that also.I bet there is some good info to be gained in that area.
