are there any benefits to switching from power steering to manual steering

[1974ChevyC10]

on my truck as of late ive been having some troubles with the power steering.the pump is bad and since my uncle built me a fairly powerful motor im wondering if it would be of benefit to eliminate the power steering.how much would a non power steering gearbox cost approx?how hard is it to swap over.other than weight savings and power gains due to eliminating drag on the motor are there any benefits to this.my friend used to have a 77 chevy without power steering and when it was moving it didnt seem any harder to drive than a power steering equipped truck.at a standstill it was kinda hard to steer but thats not surprising.any tips or input would be great.thanks in advance
