Is this with SS springs? 6deg down is the standard answer.
Any other aftermarket suspension like Caltracs etc go by what the manufacturer says. They should know.
But it is a little more complicated than that. Caution - it is more than just measuring the angle of the pinion.
You can push the search button on this site and punch in pinion angle. You will get over 150 hits. Beware many are very knowledgeable others not so much. Understanding and measuring pinion angle seems to be impossible for some.

In theory, there is no difference between theory and practice. In practice, there is.

The advice of 7 deg is to compensate for weak leaf springs. This is a recipe for vibration. A perfect set up has matching front and rear angles. 7 deg in the front is not happening.
Set it for 2 to 3 nose down and work on controlling axle wrap.

Have a smart phone or access to one? Yes, and I've fooled with it. Not accurate enough. Not nearly as good or as handy as a decent angle finder. Pay zero attention to actual drive shaft angle. Trans and pinion only. Really? Positive pinion angle - or operating angle where the pinion is nose up relative to the driveshaft centerline - is to be avoided. A leaf spring deal is likely to be a small tire with the rear housing in at or near stock ride height. Probably with the rear U-joint lower than the front joint. So you should be able to get the operating angles where they should be. A different situation from a big tire, back half type car with the engine/trans in at stock location.
If the results don't match the theory, change the theory.
