I have done a little research and a several folks have moved the box without any issues with the steering angles or geometry.
I have also found that several folks have even installed the newer power steering box with TTI headers (did require a few small dings and these were on a B block, not RB).
I have put a few front ends together over the years and the factory tolerances are all over the place. At one point I purchased a factory big block A body K frame and compared it to the 3 small block K frames I currently have and it had the steering box mount shifted slightly to the left side of the car and seemed to be at a different angle (pics are posted on this site).
I like the idea of installing and mocking up the motor and headers before I touch the K frame and see where I end up. If I feel the power steering absolutely won’t work I can always reinstall my 20-1 ratio manual box.
My daily driver is a hellcat Charger so I have become spoiled with power steering and 700 horsepower. I would like to make my barracuda somewhat nicer to drive and a big block with power steering would be a step in the right direction IMO.
