What is everyone's opinion on close ratio power steering gear boxes vs standard 4 1/4 like what's on my 67 GTO. I need to replace the gearbox, it's making internal noise. Ive heard some people say they have turning radius issues, others say they're stiffer when steering. I can get a Cardone box with the standard 4.1 ratio, which is what I like and am used to, but if people like the upgraded close ratio, I'd like to here some opinions.

This is the best steering box you can buy:

You may get lucky with a GC box for less but these are new and there are none better for steering feel and quality.

The ones with turning radius issue are using F body boxes which have internal steering stops. Works great for a Firebird/Camaro, not so much for the A body

You will pay a LOT for the box shown in post #2....& it won't do anything better than a rebuilt 2 1/2 to 3 turns lock to lock box.

I had my original rebuilt with close-ratio steering by Chip's in Missouri about ten years ago. I like it, but to tell the truth it doesn't seem that different to me.

I have run them in two vehicles; a 2nd gen F and a 71 A.

1. The F was a 79 Trans Am with a box of unknown condition - it was replaced by the then Delphi box from Ames. Compared to a WS6 box a friend had in his 79 it was night and day - especially on center feel.

2. The 71 had a reworked IROC box with stop corrections that I drove for 20 years. It was replaced by a Turn One version of the discontinued Delphi - once again significantly better.

Tell us about your personal experience here with the Delphi box. Not what you have read on the net or other heresay, actual experience.

I swapped a mid 90's Jeep Cherokee box into my 67 several years ago.....big improvement. Pretty straight forward modification.

$999. But it doesn't end there. The later
PS pumps put out more PSI than the 67.
And this has a 30 spline rag joint. Comes
with AN6 fittings. I won't lie, it sounds like
a real nice PS box, but I don't think this is
what OP was looking to do...

I wouldn't say a 12:7 box is "stiff", it's more
like they've broken away from the hyper
assist. Some folks like the "wonder touch"
steering where you can flick the steering
wheel with just one finger.

If you see 80s musclecars, or a Jeep GC, at
a used car lot, take a test drive?

I bought the 'upgraded' p/s box [ two piece with alum front end ] from Detroit Speed. It had a clunk in the straight ahead position & DS refused to replace it.
The steering was also too heavy for my liking. The rebuilt factory box that I ended up getting was just right for feel & effort for me.

The pumping mechanisms are the same for the pumps. The output PRESSURE is controlled by shims in the pressure valve, & these can be changed.
The output VOLUME is determined by the size of the orifice in the outlet fitting, bottom of the pump, where the pressure hose bolts on.

We bought ours from Lee and couldn't be happier. Great feel, no problem with the turning radius, easy install with no adapters, etc. Probably the best improvement that we made to the car.

Love my Borgeson (12.7:1)...what a difference.
