I have 3 P/S pumps, two seem to be first gen, the other we are unsure. We were looking at the brackets in Rick's catalog and cannot determine what changed between the 67-68 327 and 67-68 302 and 350. I currently have two brackets to accomodate a 69 and a few others, origin yet to be determined. Does anyone know what changed, and have pics of a 350 s/b powersteering setup? I am trying to figure what goes where and the assy manual is no help so far.

add: The more I look at this the more I think I may have a problem. The block and water pump is a 78 400sb. I am not going to be able to put a 67 P/S pump on that block and expect the pulleys to line up or can I? Hubby is out there now shaving the waterpump to accomodate a 69 s/b cradle. (don't ask) Help?

Seven's & eight's have short height water pumps, sixty-nine's have the long water pump because alt is moved over to pass side, hence different brackets.

The '78 brackets you have will fit a '69 & later, but not a 67 or 68. My P/S has a plate under the drvr isolator pad and a cradle bolting to the front of the block.

Mary Beth,
If your alternator is on the passenger side, then the PS pump should mount off the water pump boss.
Low perf engines used narrow belts, high perf like Z/28 and big blocks used wider belts with wider pulleys.

Later pumps have pressed on pulleys with no keyway and no nut, the shaft is larger than the older pumps with nut and keyway.
The PS pump should drive off the crank alone, the belt doesn't run over the fan pulley, only the alternator pulley does. But if it has air conditioning, some of those do loop over a second groove of the PS pump.

If you use a later pump with female outlet fitting, then use a PS pressure hose for a 1974 Nova. The Nova has the same subframe and engine mounting and used that type pump.

Alt is on rh side. P/S pump does not mount to waterpump boss with current brackets (69 s/b) Later year p/s does not mount either direct to block or to waterpump boss. Thinking of changing water pump but can I use orig. style for 67/68?

The later year p/s pump has not yet been identified. I don't know what it came out of. It was in a box in the car when I got it. Could be 70's or later. I just looked in a corvette c-3 catalog (Paragon's) and they show one similar to the camaro.

Yes

This item # from e-bay is real similar to our unidentified pump. Any idea what it came from?

Marybeth - Looks like you have 69 alternator setup in your 68. If you want the 68 look, alternator goes on the other side (drivers side). PS pump brackets are diff for a 68 too. Ricks has them and possibly other suppliers. I did mine recently and the AIM was VERY helpful.

Could be any number of applications. I recently installed a March Performance Serpentine Pulley kit on my '69 and had problems with the 69 model power steering pump working with the March Performance brackets and was advised by March Performance to use a pump from a 71 Impala/Chevelle. That pump looks identical to the one that I had to install (from a 71 Chevelle) on my '69 so I'm going to say it's at the very least an early 70's power steering pump.

gro51: Yes, we moved the alternator to the RH side based on the block being a 1978 400 s.b. Now we have run into P/S pump issues.

Everett#2390: Even with the 1978 block we can mount a short style 67 water pump? And it will work? Hmm, interesting. I knew the blocks were the same or similar from year to year but with that much of a span, I didn't think it would function properly.

The 67-68 327 had a 6.25" balancer the 302 and 350 had an 8" one.The 400 balancer is 8" and it will hit the 327 bracket.Also the 67-68 bracket bolts to the bottom of the block in the front old motor mount holes on my 73 400 the bosses were their but not drilled and tapped.If the engine is in the car these would be a pain to drill and tap.

Lovely, (sarcastic toward the issue, not the help) thanks for the info. looks like this could get difficult. I am headed to work shortly but will look at this again when I get home tonight. Keep the info coming. I can use all the suggestions I can get.

Mary Beth,

It sounds like you are trying to mix short and long water pump components. You can not mix them. If you want to use the '69 setup, (Long water pump and alternater on the passenger side) You must change everthing ! All brackets AND pulleys must be changed to the long water pump, type. I believe Alan Grove components, does sell a bracket to mount an alternater on the passenger side, with the short water pump. Then all components can stay as a short water pump ! Make sense ? Good Luck.

This is a pretty common later 70's pump. It requires a long water pump and pulley set. GM used this on almost every small block from around 76 to the early 80's.

Can you post a photo of your pulleys?

You can use any year pulleys, water pump, or ps pump, but you need the whole system for whichever year you pick.

Look at your crank pulley, is the first groove flat against the vibration damper? or is the pulley offset out 3/4" then the first pulley starts? If it's flat, then you have the early pulley set for a short water pump.

I have some info on pumps, brackets, and pulleys here: http://www.pozziracing.com/camaro_st...and%20brackets

Going out to take pics....stand by....

Pulleys that are currently on the car....the only thing I have replaced on the front of the block is the fan. Everything else was already attached. I have a feeling that that may bite me in the butt
