Power steering question

K, so I did a 4.3 v6 conversion and I'm at the point where I'm putting everything back on the engine. So I have a cooktops question for those that have done the v6 or chevy 350 v8 conversion. Do I use the power steering pump from the original jeep or do I use a chevy power steering pump. I wasn't sure if there would be pressure differences. I know the old pump needs replaces because prior to the build there was no power steering and the master cylinder set up seemed ok so I'm guessing it's the pump. Below is the specs if that helps.

Chevy 4.3 liter v6 with vortex
4 brl carb intake with carb
Th350
Dana 300
3 core aluminum rad with trans cooler
No air conditioning

Let me know if you have any questions.

yes keep the one on the 4.3...

just need to make sure you have a PS gearbox that is set up for o rings (newer) and not flairs (older).

I'm pretty sure it's flairs on a 80 cj7 box. Info on the napa ones would be helpful

My gear box is good. I'd rather spend the money on something else. Like a good tbi setup

wow dont know how hard it would be to bring up to speed but you could probally get an injected manifold from a blazer and get yourself a stand alone ECU and you'd be set....

THe guys out on s10forum were a big help when it came to some of my 4.3 problems...

I have the tbi manifold. Need the FBI and computer with harness. Pick and pull should take care of it I would think.
