Exhaust vs power-steering

I'm not sure what clearances I'm looking at here, being measured in an enginestand and such, but I know the engine will never sit that far and high away from the steeringbox in a normal A-body driver.

From the pics I've seen sofar the steeringbox sits at 1.5" away from the heads at certain places. And that's WITHOUT the exhaust mounted.
In your pic the box is well over 4-5" away from the head.

What kind of setup are we seeing here?
