Here is a shot of the plumbing for the three scavenge lines on the oil pan. My engine was run on the engine dyno with the dry sump pump and measured 10 inch HG vacuum. The valve covers are completely sealed with no vents. The only vent is a 4AN line plumbed into the valley cover that goes to a remote breather.
Here are some shots showing how I routed the plumbing underneath.
You can see the plumbing in the left side of pictures tucked up next to the frame rail and sub frame connectors.
I also up-sized my exhaust to 3" all the way back for the new engine. I bought some mandrel bent tubes and had some tubes custom made...
then fit and welded the tubes. This was my first time to do my own exhaust.
These shots are from the back of the car looking forward... the oil lines go up into the trunk and attach to the oil tank.
I ran the oil lines up above the new cross member that came with the T56 Magnum... this worked out good to keep the lines away from the exhaust.
