Is there a generic pinion angle for an 8.75 to an a body

[Taylor-Made]

I am putting in an 8.75, for street use, is there a general rule for the angle of the spring perches? I am not planning on running this for the drag strip, just to keep the rear end under the 340 and not to need a wrecker the first time I get on it?

You generally want the pinion 5-7 degrees nose down for leaf springs but if your not racing it you can run less. Here's a link to an article on Moparts that describes it.

what is the advantages of goin more either way?

None really. You want just enough angle to cancel out under acceleration (the rearend twists under acceleration) or you'll eat u-joints and bearings and may have a vibration. Read the article on Moparts I posted. It tells all about it.
