I am changing out the 350 for a 455 in my 69 cutlass. When installing the aftermarket Holley headers we had to move the brakes proportionate box to allow room for the header. Not sure why that had to be done. Figured the car was designed to handle the larger motor. Anyway I want to just reinstall this box on top of the frame rail laying flat vs. on its side. Does anyone forsee any concerns in doing this? Not sure of the inner workings of the box in which it has to be installed on it's side. Another thought is to move it down and back on the same frame rail.

 

Just be careful to avoid kinking or bending the lines. Otherwise, I don't see a problem.

 

That's the way it's done, all right. On top of the frame rail and watch kinking the lines.
