Power Steering on an L6 250

My '69 GMC has no factory power steering. I found a power steering pump bracket on e-bay a while ago for this engine, but I'd like to get a bit more info. Does anyone have pics of an L6 engine with power steering? Where does the bracket attach? Will I have to change the AIR system?

Re: Power Steering on an L6 250

You have to have a pulley for the crank.I say this because I have 2 bracket set-ups and no pulley for either.One I pulled off and didn't get the pulley(DUH) and the other I got from a friend who didn't have the pulley.

Re: Power Steering on an L6 250

Here's a couple. I got the hardware from a Nova. The mounting bracket that the pump sits on and attaches to the head I got from the Chevy dealer about 15 years ago. It didin't line up so I had to cut it. Your best bet is to find a 70's type Chevy or Nova six cylinder to get the mounting hardware from cause they're hard to come by.

Re: Power Steering on an L6 250

blue C10, also be aware that there are two different types of brackets for the 250,The one that came on the integral head engine(where the intake and exhaust manifolds are part of the head) must be modified to fit the non-integral head engine.I don't know the exact mod but someone here has done it(I also can't remember who)

Re: Power Steering on an L6 250

Here's a few more pics someone posted a while back. First one is the parts breakdown but may not be complete. Also, the pulleys are different. I have the double pulleys on mine. The others show a better pic of how it's mounted.

Re: Power Steering on an L6 250

There must be 10 different PS systems for these six cyl engs...different brackets & offsets, different pulley setups, drive pulleys, etc. I work on quite a few of these and unless you have boxes of spare parts to get everything to line up, I always strongly recommend you get a "complete" operating system off an engine.
There are guys on here spending months trying to get the right parts. Good luck.
NOTE: You are looking at three different systems in the pics above and none of them are stock for our trucks.

Re: Power Steering on an L6 250

Does anyone know if there's a decent flow stock exhaust that will replace the stock manifold on a 78 Chevy L6? 90's model Jeep looks close...
