steering box

[markm]

Thanks Rick, I believe a 605 made its day view on low cost G bodies like the 1978 Malibu. Most I have seem have had the optional Saginaw. A far as clearance goes I don't understand I have headers on the 396 in my 55 with a CCP500. Yes its tight, but its a BBC. As far as Cnuts chart goes he must have cut and pasted that from somewhere, that missed an important point. The early 800 Boxes were junk, example the one on my 67 SS 350 had no road feel, the one bolted in place from a 77 Z28 with variable ratio was wonderful. I had similar results on my 70 Chevelle SS 454 using a later Trans Am box.

Found this explains my results. http://www.hotrod.com/how-to/chassis...g-box-upgrade/

There a 605 box conversion that was "the thing" to do for many years. Lots of cars used these power steering boxes.

The 605 is kind of like drop spindles. They were the thing back when but now better used as boat anchors LOL.....

I still say you're wrong about dropped spindles. They're a better way to lower the car than screwing up the suspension geometry by angling the lower a-arm up.

To expand on markm's comment, the Saginaw 800 boxes have 2 or 3 things going for them that 605s don't. One is that the factory had several torsional hydraulic valves from loose to tight, and choosing the right one can really make a difference. Also they made different ratios through the years. 16:1, 14:1, and 12.7:1 variable - again you can choose the one that suits. Any valve and any ratio can be swapped into most cases, or the whole unit can be swapped. They were also manufactured from the 60s through at least the 90s (my 95 truck had one, tight valve and 12.7 ratio).

The 605 was only manufactured for a few years (79-84 I believe), and the valve and ratio were the same in all.

I've been studying this debate for a bit. I will post some comments soon. My current thought is that the real answer is somewhat between your positions, but I haven't completed my layouts and analysis of them yet. I can say that dropped spindles will be a benefit.

The only reason I mentioned the 605 is that it IS an alternative that was used by a lot of tri5ers over the years, and many still use it despite it's deficiencies. It's a viable alternative to the stock box, which is what the OP originally asked about.

[Rick_L]

You are right on that. And there have to be 605 boxes out there for sale cheap. In fact I have one that I haven't offered yet. That will fit the budget of some.

Cnut keep polishing that turd. I'm personally not concerned about your bolt design. If we are going to discuss fatigue I'd be more concerned about the aly C4 parts 50 years down the road. Rick keep studying it. I'll be in Bay Town Texas on June 12 and you can plop your azz in my car and take it for a spin or I'll gladly scare the living sh.. Out of you in it if you wish and end this BS lol. Nut my work is shown in the last post of the thread you called me out on. It matches every thing you googled and posted in prevoius threads in an attempt to say I'm full of it. And your Cowardly ass never even responded.

And for the record Rick and to stay on topic it has a 500 box lol.
