Hydro-boost Question
Has anyone done a swap into a 67-72?Can I use the original p/s gear on the truck?Are hose fittings a bolt-up?The hydro-boost is from an`86 diesel(6.2),what can I use for pump brackets on my 350?Do I need to find a 350 equipt 1-ton in the junkyard?Would the 6.2 brackets work,by chance????

Re: Hydro-boost Question
Do you have power steering now? If so your power steering pump will work fine.

Re: Hydro-boost Question
I was in a wrecking yard yesterday and noticed a late a couple 70's/early80's caddys had hydo-boost set up. I have one on my 85K30. IIRC the power steering pumps are different, they have 2 Hi-pressure lines and one low pressure. I'll see if I can post a pic for you tonight.

Re: Hydro-boost Question
Thanks,I have the complete system on an`86 diesel Suburban.It looks like mounting on the 350 will be the only hurdle.I`d be amazed if I could just swap the bracketry from 6.2 to 350.I`ll prolly have to get that from a 350 equipped 30.

Re: Hydro-boost Question
Here are the pics, I had to wait for the rain to stop. There are 3 line ports on the PS pump. The PS brackets are plain ol' long-nose power steering type used on 73 & up. The motor is a 350 Eldebrock crate.

Re: Hydro-boost Question
The low pressure return line from the hydra boost can just be T'd into the low pressure return line from the P\S gear box. No need to get a special pump.
