So I thought I had it all figured pot, a 500 siries power steering for my 55 chevy but every time I say that someone will ask why not a rack and pinion steering. So for those of you that have gone to power steering I'd like to hear the pros and cons on this issue.And I will continue to do some more research, Thank you in advance.

Certainly r and p eliminates all linkage and sloppiness of the gear box set up. But the conversion and installation is more complex. The difference in my 51 with a power 93 Mustang Gt rack was dramatic compared to the basic 30's design that was oe. Your car had a much better steering then the 51, to begin with.

There are quite a few choices today for power steering. Some require solving many problems to make them work well, like r&p, some are simple bolt on jobs, like the original linkage type PS, and some in between, like the 500 PS gear, and even electric power steering from EPAS.

The way your car is equipped now will eliminate some of those choices. For example, if you have a column shift manual transmission, you cannot install any PS gear including the 500 PS gear. EPAS electric power steering cannot be installed with ANY column shift transmission. R&P is difficult to install with BBC and some headers. The OEM linkage type PS is probably the most versatile system but the existing manual steering gear must be in good condition and adjusted properly to get the best performance out of this system.

No my options aren't limited since My original plan was to put a 700R4 behind a zz6 engine, an Ididit coloum shift. All the frame is cleaned up and ready. I was going to just rework the front end and put a 500 series P/S box and I may still, I just have to decide which P/S I'm going with.

Yeah I'm sure I'll run into some issues, that's why I'm going to do as much as I can while the frame is off. I just got the suspension off boy what a pain, going to shop around an see what it will cost to redo all the ball joints,bushings and all the rubber and weigh that against going with something new.

It is the metal tube over the steering shaft, it needs to be shortened due to rag joint and split shaft,
It has the wires inside it for turn signals, horn

Our 56 was already done when we bought it. Had the 500 series CPP box installed. It drives good. Even with the big steering wheel it easy to turn stopped.

"Even with the big steering wheel..."

Big steering wheel decreases steering effort, doesn't increase it.

Back to the problem at hand, a CPP500 or Borgeson 670 box is far easier to do than a rack and pinion. All of them require a power steering pump, so that problem is the same for all. R&P also requires changes to the steering column, though the length requirement is not as precise.

If you are keeping the stock front suspension, a p/s steering box is far easier than R&P, as R&P usually has difficulties with routing the steering shaft past the exhaust. Not that it can't be done, it's just easier with fewer compromises.

The other half of R&P is that it's good to use with a frame/suspension designed for it, like a C4 front clip, aftermarket frame/suspension etc.

I don't know what a C4 front clip is, but you just said exactly what I have been thinking. So at this time I'm still thinking the 500 series power steering box an I'd did it steering coloum and the stock suspension reworked. I will listen for more options before my final decision .

4th gen Corvette (1984-96). This is the first significant suspension change since 1963.

Those who choose an automatic transmission want transportation. Those who choose a manual transmission want to drive.

But this bolt in took me a few months to do.
As reported when I got it done, it is one finger steering with the 1970's little steering wheel, and it is kick ssa.
And I have the 13" Cal Chrome ? Kinda steering wheel.
As Jalepeno said, it steers like a go cart.
Poor mans bearing........waste of time.

Yes I understand this, What I was trying to get him to understand it is very easy to turn the wheels even at a standstill.

Frankman, when rebuilding your front end, regardless of the PS choice you make, get new upper a-arms that have an extra 5 degrees caster built in. Additional caster will really help tracking. Cost is about $200 for the pair. They are fully assembled with bushings, shafts and ball joints, ready to install.

You can rebuild your original a-arms with new bushings and ball joints but you'll still have the stock 0 degrees caster at most. With the cost of the parts and having the bushings installed, it's about the same $.

Ok I was thinking about ordering the complete front end suspension rebuild kit, but I think the control arm is probably like the original.I'll have to ask.thanks for the info, I'm also thinking about ordering the springs that will drop the front end an inch and a half or so.Boy I'm sure glad you posted this today as I was going to order the kit tomorrow. Sometimes I feel like I'm trying to move to fast before I get enough info, maybe I need to slow down and allow the info to come in.Thank you I appreciate the help.

You have the right idea, take a little while to digest the good advice you are getting. You will be so much happier when you make informed choices.

Ok Jalapeno been reading up on front end alignments to get some understanding. So if I were to buy the upper control arm with 5 degree positive caster, can it be adjusted from 0-5 or does it stay a 5 degrees positive.And I imagine alignment tech's are used to dealing with this issue.

Adjustment range with the shims is only maybe +/- 1.5 degrees or so .

In other words you are going to have 3.5 - 6.5 degrees of caster.

Not a big deal unless you install these control arms with a manual steering setup, because steering effort will be a bunch.
