I built a 70 a-body years ago with a 440 and used b-body hp manifolds. As stated, the passenger side is the same. I had manual steering, but I am sure power steering would work too. All I had to do was shorten the steering column housing about 2 inches and everything fit well. Clearance was tight, but nothing hit. I started with a small block k member and used Schumacher mounts. The c-body driver side outlet, is higher up and more angled than the b-body manifold. I'm not sure it would clear the column. Also a low deck engine would give you a little more clearance.
