Pressure out has more to do with steering brand than year. Bendix which was used from introduction thru 56 will range from 550 to 800 psi. Starting in 55 Monroe units which were also used along with Bendix have extra springs in the pump relief valve to raise their pressure range to 650 to 900 psi. Pumps except for relief valve are identical in operation and looks. Identifier is Monroe pumps have a 900 stamped on the output port and there is a caution not to intermix the pumps as it will cause erratic action and noise issues.
