short water pump and alternator on passengers side, will this work? need pics

stock exhaust or headers? I"m just wondering if this would work and which brackets would be needed for the short water pump set up? Thanks!

Re: short water pump and alternator on passengers side, will this work? need pics

The alt on the passenger side was in the GM cars. The alt brackets were based on a long water pump. There might be brackets to do it with a short pump... but I have never seen it. Not sayin' it isn't possible.

Not to mention you have to reroute all the wiring.

That's actually a long water pump.
GM cars ran short pumps on BBC and SBC thru the '68 model year.
They switched to long water pumps in the 1969 model year.

Chevrolet and GMC trucks used the short water pump thru the 1972 model year.
(also BBC and SBC)

I've never seen a factory set-up with a short pump and the alternator on the passenger side.

PUt some pictures up of your engine. So we can help you. I just went through this same problem a couple days ago. I bought the chrome brackets just like one above that fits 69-81 or 85 gm long water pump. So my alt goes on passenger side.

Re: short water pump and alternator on passengers side, will this work? need pics

here's what I'm working with. If I put(leave) alt where it is, the belt hits the ps pump for my ram assist.I have the correct short water pulley,but like I said, the alt belt will rub on the ps pump. Will a newer style pump, which I think are smaller, have the same fittings for the hoses that connect to the ram assist manifold? Also note that my Weind intake has no hole in the front to connect brackets to.

I also have 2 different sets of headers I can use, if I can make this work.

Re: short water pump and alternator on passengers side, will this work? need pics

You've got 67-68 style brackets that require the mount on the manifold.
If you go to 69-72, you can keep the driver's side alternator, as it will mount to the head, not the exhaust. Also get a shorter belt & it shouldn't interfere with the pump.

Re: short water pump and alternator on passengers side, will this work? need pics

I'm looking at your pictures again and think you'll have to go long pump for the alternator to clear those valve covers

Re: short water pump and alternator on passengers side, will this work? need pics

I would just use the correct 67-72 truck alternator bracket.
No need to worry about a header bracket.
These two are all you need.
(the lower bolts to the front of the driver's side head)

Short water pump with a bracket from Summit. Just be carefull cause the internally regulated alternator positive terminal starts to get near the valve cover, if you go that route.

Are you sure? Because that looks like a long pump.

That is also a long water pump.

It's really easy to verify.
Just measure if you are unsure:

Re: short water pump and alternator on passengers side, will this work? need pics

oldgold70c10-I had a long water pump on it when I started and the ps pump pulley wouldn't line up. As far as changing the length of the belt,it doesn't change the distance of how close it is to the ps pump...I tried.

lolife99-the alt head mount might work, but I have no bolt hole on my intake for the other bracket. Also I've tried the newer(69-72) alt bracket and the alt would hit the valve covers before I could make any belt adjustments.

my67c20- if I can get the correct belt and bracket set up to fit, what I've done in the past, is to take the 4 screws off the back of the alt. and just turn the back of the alt connections where I want them. Just make sure to use a paperclip to hold the brushes in place while you do that.

Does anyone know if the "white"(manifold block?) has the same fittings as a power steering gearbox.

Maybe I'm just beating my self up ove this, but it's alot easier to make changes now while the front clip is off.

The tall valve covers may be a problem,... but the upper bracket doesn't bolt to the intake.
It installs like below:

Re: short water pump and alternator on passengers side, will this work? need pics

The long water pump set-up places the entire alternator in front of the engine.
So no there are valve cover clearance issues.
This might be your answer.

But all of the pulleys are different.
The P/S stuff is also different.

Is this a short pump? Would it be possible to make my setup a 1 belt system?

Yes,... that's a short water pump.
(I've never seen a 1-belt set-up)

Most truck bracket assemblies include a "add-on" P/S crank pulley, that bolts on top of the existing crank pulley.
Then a single belt drives the P/S pump.
The other belt goes around the crank, water pump, and alt. pulleys like normal.

I want to thank everybody for all the information. I'll see what I can come up with sat or sunday, and let you guys know how it works out. This is just the first "ram assist" system I've ever messed with.

Re: short water pump and alternator on passengers side, will this work? need pics

Just saw this thread now. You can do anything with time and money! I changed my alternator over because it was on the 'wrong' side. Didn't want to use header bolts at all, so just drilled an extra hole in the right side head and made the bracket bolt staight to the head. These brackets aren't commercially avaliable, but I could maybe get you a set.

When it comes to long vs short, everything is different. The pulleys are different, the brackets are different, etc.

Go to the 73-87 parts board & find someone parting out a truck & get the pulleys & brackets all at the same time from the same vehicle. Everything will line up & you'll not have any clearance issues.

Re: short water pump and alternator on passengers side, will this work? need pics

After i sent the post i realized it was a long pump. I figured there were enough experts here that would quickly point out my error. The short hit the timing cover. but i still had plenty of room in front of the radiator so i went with the long.

I can't believe no one has suggested this yet (or maybe I missed it), but you could pull a complete serpentine set up off a newer truck and be done with it.
