'66 Chevelle SBC power steering conversion problems

I am trying to do a manual to power steering conversion on an '66 Malibu with a 283 and original exhaust manifolds. I am stuck. I have not been able to get a pump that will work. I have bought the aftermarket lower cradle and upper bracket that everyone sells so I have to assume these will work.

I have searched for pics of an installation with stock exhaust manifolds for hours but can't find one. I can find them with headers or with a BB but not a stock SBC. I have the 1966 Chevelle Assembly Manual and I can see all the parts for mounting the alternator and power steering pump. It looks like I have what I need except for a pump that will work.

I have ordered several pumps from different suppliers but never seem to get the correct one and never the pump that is shown on the website. Regardless of where I purchase them, they all seem to come from the same rebuilder and no one can specify which style pump I will actually receive. None of them work. Either the lower alternator bracket or the boss on the exhaust manifold for mounting the alternator hits the pump reservoir neck or the lower cradle hits the steel tube for the fluid return line. And the exhaust manifold may get into the high pressure line on one of the pumps.

What am I missing here?? This should be simple. Can anyone please help me figure this out? Thanks.

My Malibu has a 327,but I'm assuming the pump and brackets are the same on the 283? I know that the pump reservoir is Chevelle small block specific,the filler neck is shaped differently than the other small block applications of that era.
I can send you some pics if you PM me with your contact info, I can email or text some to you.

Re: '66 Chevelle SBC power steering conversion problems

I have my 1967 327 pump and bracket in the garage that I pulled putting on one from a 1990 C1500. I can get you info from it if it would help. I still run iron manifolds, but when we put in the ZZ4 I know we had some issues with accessory mounting due to everything basically hanging off the water pump in 1967.

Re: '66 Chevelle SBC power steering conversion problems

Thanks Ed. I assume the C1500 pump bracket mount to the heads on the ZZ4 is why you could change to that? I'm sure 327 and 283 Chevelle bracketry was the same in '67 and '66. I think it is the same from '65 to '68 as is the pump. If you have pics of the old brackets it would be helpful. BTW mine is a non AC with alternator on driver's side.

I have a 283 w/exhaust manifolds on my ‘66 and power steering pump, probably original?

Not sure why you can’t find a pump that fits, I’d imagine any stock style pump will fit.

I’ll get some pics of mine, maybe that’ll help.

I changed everything on the front. I went to a serpentine setup with a long pump. I used the alternator/ps pump/water pump/brackets/fan, all for the 1990 C1500. Besides the obvious reasons, I also planned on the possibility of A/C later, and that setup had a dummy pulley for a/c location which I just dropped in a compressor with no other change.
I will dig out my old p/s pump. Feel free to remind me!

Thanks for the pics! Yep that is the pump I have been trying to find. I can see that you have the same lower alternator bracket as me. I have now ordered 7 pumps that were supposed to look like that and so far none have been correct. I have learned that the pump is Chevelle small block specific for these years ('64 to '68 I think). The reservoir neck is shaped differently to not hit the alternator bracket when adjusting belt tension and canted forward to clear the exhaust manifold.


A couple of restoration parts suppliers have noted this problem and have have is supposed to be the correct Chevelle pump. I have #8 on order and have my fingers crossed. At least I know now exactly what I am looking for (I think).

Re: '66 Chevelle SBC power steering conversion problems

Here is mine, a couple years later and it is still leaking out the hoses! Ignore that 3rd hose, that is from the JGC I cut.
I obviously did something weird cropping them, but ignore that. If you want anything detailed, let me know. Also if there is any identification marks to check, let me know. Otherwise it will sit in the garage untouched for more years to come.

Re: '66 Chevelle SBC power steering conversion problems

Hi Don, I am about to undertake a PS conversion on my 66 as well. Do you have a list of which parts you sourced for the conversion? Did you use a JGC box? And if you manage to find the right PS Pump please let me know, I am running a 327 with headers so I don't think clearance will be an issue, but better to be safe than sorry.
