Hi Everyone.
I am changing my manual for power steering and someone has offered me a later mid 70's style pump. Will I be able to get brackets to fit my 68 327? It's to work with a 68/69 steering box.
It will work. Just get brackets for whatever water pump you have. Example 69 had a long water pump. If you have the long water pump, brackets are relatively easy to find. I like the mid 70's to early 80's truck one piece bracket. Very easy to work with. Or you could buy aftermarket brackets from a company like Zoops. They make quality parts. Hope this helps.
The trucks used the short water pump for much longer than the cars did and have a couple different bracket and pulley setups out there that are readily available new and used. They used an add-on second pulley on the crank that went over the exiting single groove pulley to drive the power steering pump.
Power steering on some used a pulley that was in the 2nd groove position and some used a different pulley that pushed the belt out further closer to where it would be on a long water pump pulley.
Some also used a mount point on the front of the exhaust manifold and others did not.
You need to make sure you get the brackets and pulleys to match or the belt will not line up. I got all the parts I needed to replace the missing system on a 68 C20 truck I am rebuilding from an early 70's van.
Out of curiosity what gear box and rag joint are you using? I'm gathering parts for the manual to power changover and settled on an AGR variable ratio box with a Dorman 13/16 coupler from Amazon. Also ended up with a Moog long pitman arm from Amazon. I got the AMD-W-095 brackets from Summit as well as the hose. I still need a pump and pulley too.
I haven't gotten that far yet. I've been offered some parts at a reasonable price. But I'm trying to decipher if they will fit first.
This is the pump I've been offered.
Keith are you suggesting the even though it has a pulley it may not have a correct offset that will fit a short pump if this is off a long pump block?
Our pump bodies are the same but it is hard to tell from the picture if the pulley is the same offset as mine but the part number on my P.S. pump pulley is 458553-AC. The add-on P.S. crank pulley that matches it is part number 3744043BA. Hope this helps.
I have a few pictures of the brackets I can dig up if you need them.
Thanks Keith. From our chat I've decided to get a reconditioned unit that is meant for my block. Can you comment on the quality of cardone units? Rock auto sell them and they are a good company to use as their shipping rates to the UK are very reasonable.
The power steering pump will fit either the short or long waterpump. The offset is done with the brackets. If you have a short waterpump use brackets for a 67/68. Stock brackets are found at all the repro houses.
The later pump will "work", but you might not be happy with the angle or direction the return tube on the reservoir. I tried one of those "canned ham" rebuilt jobs on my 69 and the return tube shot off at some ridiculous angle and it looked stupid. This is because the later pumps are likely for a car with the steering box out near the front of the car vs the 1st gen Camaro which is closer to the firewall. I took it back to NAPA and exchanged it for a rebuilt pump w/o a reservoir and re-used my original reservoir. Since you are doing a conversion, just a potential problem that might pop up.
67 - 69 pumps use bolt on pulley with keyway. Later pumps from 1974 up use a press on pulley, no keyway. Your photo shows a later 70’s press on type. The shaft diameter is larger on the press on & wont interchange.
In 69 GM went to the long water pump & there may be a pump pulley press or bolt on that would work with the later press on pump.
Since you have a short 67/68 water pump, use the bolt on type pump & pulley. It is very doubtful you will be able to find a pulley to work with short water pump setup that is a press on type. The shaft can be changed if you had one but it requires full disassembly of the pump.
68TT, You have mentioned an issue I've only just come across. I've made a large order for everything I should need ( 50% chance of getting it right first time! Hah) but I need to get the crank pulley from somewhere else. As well as a new balancer as mine wobbles but that's another subject. I notice there are lots of different types as usual. I think this 2 groove pulley would be correct. https://www.summitracing.com/parts/clp-cp9481s/
David, thanks for clarifying the later pump pulley issues. I've decided to buy a reconditioned original style pump. So hopefully I will avoid retro fitting issues. My engine bay is completely stock and i like to keep it so.
Also may I say thank you for your fantastic website. I've recently been replacing all my suspension components, I've found its been my go to manual and main source or research.
Please keep it up.
You need a three groove pulley for short water pump. Normally GM used a one or two groove crank pulley & added a third pulley bolted inside to drive the ps pump. This one is probably the one to use but I can’t guarantee it: https://www.summitracing.com/parts/clp-cp8858p/overview/
Ps pump drives off the third groove.
Be aware the stock pulleys used on low or standard performance Camaros are narrow groove. Z/28 used deep groove special high performance pulleys that worked much much better for high rpm applications. The crank pulley sets will not mix & match between std & high performance. The deep groove ps pump crank pulley insert has more offset forward & wont line up with a low perf pump pulley.
David you mentioned on your page you put a high PF pump bracket on to clear the bigger vibration damper. I need to change damper, are you suggesting that I may be better off putting the larger one on? It's a stock 327. Thank you
