The 67 with the LS1 looks immaculate. I hope I can find a good LS1 engine for a fair price. Sounds like you've got skills the rest of us would envy. I think the hoses and fittings are difficult to find and get right for cheap. I went to a Parker Store for power steering hoses and fittings and ended up paying $90. It was more than I expected for hoses/fittings.
Did you use an in-line filter in the return line? PSC has a 35 micron filter in their kit.
Did you use a remote reservoir? My current saginaw P series pump has a ~0.5L reservoir capacity. The PSC reservoir is 1.3L and I believe the larger capacity makes a power steering fluid cooler unnecessary. I don't know if I have a good place to mount a remote reservoir.
What proportioning valve did you use?
Thanks for the compliment. I am very patient when I want something a certain way, & I can also be very frugal, so I do a ton of research before doing anything.
Here's something similar to the hose I used....
Although you'll need hose rated for 3000 PSI. I'll try to find the receipt for the hose I used.
I used the stock LS1 F body PS pump with the attached plastic reservoir & modified the stock pressure hose to accept the black braided hose. The pressure hose from the pump has a crazy bent end with a 3/8" flare fitting that needs to be utilized, so I actually took it to a local hose shop with a length of braided hose & had them crimp the ends on it for me.
Come to think of it, the hose shop crimped the ends of both pressure hoses with standard AN fitting they had in stock. The return hose I made with fittings I picked up from Tallon Hydraulics. I think it cost me around $200 all in for the 3 hoses. I didn't use an inline filter, but it couldn't hurt.
I ran a Jeep GC steering gear, so I used a fitting like this one for one of the pressure hoses to connect to the box....
The fitting for the return port of the hydroboost is similar. I bought both of them from Tallon.
The proportioning valve was the standard brass block version from Right Stuff, etc for Disc/Disc cars. It's the same made in china piece all the vendors sell. An adjustable one isn't needed, IMO.
