Rear Pinion Angle/Leaf Spring '67 Camaro

[67rally]

I've read non-stop for a couple days now and can't seem to find a concensus...

What are you're thoughts on the ideal rear pinion angle in relation to driveline angle on a 1967 Camaro. With the subframe level, my driveline angle is at about 3.5* down, and I may be able to get to 3* down with shimming the rear of the trans up, but I'm getting very close to the tunnel.



-Hotchkis 1.5" rear lowering leafs/Hotchkis 2" lowering front springs
-Bilstein shocks all around
-Solid aluminum body mounts
-LS/T56 458hp/410tq
-Strange S60 rear w/4.10's


-One school of thought says the engine/trans should be pointed down (3* ideally) and the rear pinion angle should be equal but opposite (3* up).
-A variation on that says they should be equal but opposite, but then angle the rear pinion down 2* (roughly) to allow for pinion wrap = (3* down/1* up)
-The other school of thought says the engine/trans should be down 3* and the pinion should be down 3* as well to allow for pinion wrap (5-7* in a leaf spring car)
