I was told by a couple of different mechanics to not run a power steering box without the power assist, it wore the recirculating ball and worm gear very rapidly, some about softer parts. I tried the removing the belt trick a couple of different times and could not see any change in performance at the track. Switching to a manual box is simple and gets rid of the power steering pump but saves very little weight. It seems like my power steering box was an aluminum housing and the manual one was cast iron, so the little I saved by losing the pump was offset by the weight of the manual box.

That's the opposite of what I've seen on these cars. The PS boxes are cast iron and the manual boxes are aluminum. Quite a bit of weight reduction by going to manual steering. Not to mention more room around the engine since the manual box is a lot smaller. A power steering box w/ no help from the pump is a lot harder to steer than a manual box. All 4 of our cars have manual steering b/c the factory Mopar power steering is too easy and sensitive IMO. I have a manual box in my garage right now from an 1964 B body, it is cast iron. The power steering box I took off my 72 Cuda was aluminum and it was wore out. My 1970 Road Runner had manual steering and it was cast iron. If they used aluminum boxes on manual steering, I suspect it was in the late 70's and early 80's. Danny Not saying you're wrong, but every old Mopar I've messed with from '67 to '75 or so...the power steering boxes were cast iron and looked like this...

And every manual box on the cars I've seen looked like this and are not cast iron...
I have 4 cars at home, all manual steering, two '69s, one '70, and one '71...all look like this...not cast iron. These are factory original boxes too. Pretty sure they are aluminum, they might be pot metal or something, but definitely not cast iron.

More reading... If you’re a purist, then your options are somewhat limited. The factory Chrysler power unit (with its accompanying pump and high pressure line) tips the scales at over fifty (61 pounds if you include the weight of the steering fluid). Disregarding its power-assisted 15.7:1 ratio, the drag of the pump pulling off of your engine’s crank pulley is rated at a loss of 10 horsepower. Equally, the standard Chrysler manual steering box has a 24:1 ratio, giving it a lock-to-lock of 5.5 turns. Made from aluminum, Chrysler made two castings of the manual box, but weighed the same at a paltry 12 pounds. from... http://moparconnectionmagazine.com/gallery-boxed-in-with-flaming-rivers-manual-steering-box/
