Is the steering box original, or has it been swapped to a newer style? When Dr Frankenstein transplanted a 350/350 and a Cadillac power steering box into my '59 Apache he created all kinds of clearance issues (especially with the exhaust manifolds).
His solution was to install a drivers side exhaust manifold that dumps out the front. I think it looks like heck. That is another issue that I will need to address in the future.
