Update-
I was able to go work in the car on Thursday. Fitting everything together as I had it, the driveline angle was approx 5.2 degrees down. That included the Holley supplied spacer (for the magnum). We started raising (and mocking in different spacers) the trans level. Ended up going to the local hardware store and bought a 1” square block of aluminum. Thanks Scott D'Alessandro!
We installed(mocked it in) that spacer and it was right at 3 degrees, closer to where I wanted to be. The contact area on the case I was concerned about is no longer a factor.
Obviously the block will have to be drilled and the mount studs will be swapped for longer bolts.
I plan on trying to raise the trans level a bit more, I know the 3 is good, I really want closer to 2 degrees. I will update more once it is in the car. The trans tunnel will have to be cut/raised. The subframe holes will also need to modified to match the new crossmember location.
