Chevy BB Power steering pump with dual inlet options or modify my current?

[cactuss4]

I have a power steering pump currently running my Jeep steering box and I'm working on a part list and waiting for parts to come in to go to hydroboost, so I'm looking at either replacing my power steering pump or modifying it to have a second inlet (don't want to run a T).

Not sure I want to try to drill my current one, so wondering if there is an off the shelf unit and I'll just sell this one.


Ahh it's a 396, This one has a 2 belt pulley.

Missed this yesterday when I was searching. So maybe this one??

But trying to find a pulley for that doesn't seem to be so easy. Everything appears to be key way. the one on my car is a bolt on (keyd), but all pumps that have dual inlet appear to be press fit, so now anyone know of a BBC power steering pulley that presses on?

Thanks

I would look at the pump from any of the C30 Chevrolet trucks up to the early 90s. A lot of them had hydroboost and still ran the v-belt setups until the body style changed in 92. Also the old 6.2 and 6.5 diesels ran hydroboost as well.

I picked up an '86 1 ton Chevy pump at my local parts store for about 60 bucks. The pulley is a Dorman I ordered from Summit (I think). It's not pretty as purchased but it will get painted eventually. I made an adapter fitting to plumb it for AN lines. 3/4" barb to -10 AN.

The fitting.

I was at the shop earlier and snagged a few pics from a 91 TBI 454 with Hydroboost. It is a remote reservoir setup with a 2 groove V belt pulley. The reservoir is shown at the top center of the engine, just in front of the thermostat housing.

Cool thanks.. didn't consider remote reservoir.. Hmm well more parts come in today so I'll see what I can make work

Okay so I've test fitted the dual inlet pump that I got with my BB power steering pump brackets and it's a go (of course Tory, they didn't make many changes with the saginaw pumps, ya ya ))

Well anyways http://smile.amazon.com/gp/product/B...?ie=UTF8&psc=1



That pump appears to work (I need to press the new pulley on to verify there is no gotchas with my belt setup but I think it will be fine...

I've got a machinist friend popping over tomorrow to see about cutting off the end of my hydroboost pump and threading it to accept the Brake Pedal Clevis.. I think I can just have him cut it off at the base of the eyelet and I may just be able to go cleavis only vs the extension rod, but I have it just in case.

Then it will be plumbing, I'll get things mounted and sorted and then grab some sizes so I can look at other OEM (GM) variants of the high pressure hoses and see what works the best (can't have too short and would rather not have too long ).
