Now that I think about it when i had my 8 3/4 the tranny was -3 down and the 8 3/4 on the snubber pad was +2 up and the driveshaft was 0* I believe... i did what the mopar muscle mag article said and measured off the snubber pad and the driveshaft and I was 2* up.... I put in a lowering block (cut) to get ideal piniona angle...

now off the tranny centerline -3 and the snubber pad it was +2 I was -1 down that way.... and +2 the other way thats a 3* swing which is alot to me

Now note.... I am no bracket racer but after the 5th pass setting the pinion angle up the way mopar muscle said on the return lane at cruising speeds i developed a slight vibration and no vibes under acceleration.... I am thinking i gave myself way to much pinion angle and that could be why my 60fts sucked also with the vibration... 1.78 was best i could muster.... BTW when my 60fts went down my mph kept going up.... I am no bracket racer but tried...

maybe someone can make sense of it all.
