Ok so I have a 1971 non AC 455 in my 1969 cutlass. I have a two groove pulley on my water pump and the fan is bolted to that. The fan is from a non AC 1970 vista cruiser. I have a power steering pump from a 1976 olds 455. I have all three brackets. My issue is when I start to mock up the pump (in car) if i bolt it up where it goes, it will hit the fan. The pump has double groove pulley on it. I am not sure why this wont clear.

Any thoughts? I can post pics if need be

Pics will certainly help, but a non-A/C 69 should have a single groove PS pulley.

 

KG stamping, specifically.

Is the WP the correct length such that the correct crank [KB 399402,
2g, 6.4 x 2.2"] and fan [KE 399401, 2g, 7.10 x 2.0] pulleys align correctly? Do you need the WP/pulleys database?

 

i think you are right with the single groove pulley, i am nearly certain it will clear the fan being set back that much further. the current crank and wp pulleys have two grooves on them. i found a single groove pulley on EBAY that is $30

i will take some pics of the motor in the car and the pump itself and will post them later today before i go further

thanks for the help

When i went to put my single groove pulley on my power steering pump, i noticed that my water pump pulley only has one groove. Right now the water pump has one groove pulley and the crank has two groove pulley. Alternator lines up with outer groove on crank and with the single groove on the water pump. I have no groove to mount the power steering. Can this be done with a single groove pulley on the water pump? I found a picture via the link below that shows the setup with a two groove pulley on the water pump....

so my question, any way to do this with a single groove pulley on the water pump?>

One groove pulley like I have on now

Like the chart shows on Ebay for the 68 to 70 455 non AC clearly shows a 2 groove pulley and on my 69 I have a 2 groove pulley on the water pump and the crank and a single on the alt. I dont have power steering but it would work with it if I installed it but like MD Mechanic said what length water pump do you have because that is what throws the alignment off many times.

 

Correction Octania! anyway he is right about the length of the water pump!

 

Should be KM or KN stamped on it. Crank pulley should be KJ I believe.
So long as it's spaced correctly, the fan could be from anything with the correct bolt pattern.

That won't work. 76 2 groove is a KA i believe, and the spacing is way too far forward. You will need a single groove KG steering pulley as previously stated.

You have 3 brackets, but are they the correct ones? Your alternator should be mounted on the passenger side on a non ac setup. If your brackets locate the alternator on the driver's side, you are mixing AC and non-AC parts.

There are most likely 2 reasons for this: Incorrect water pump length, and incorrect pulley spacing.
You need a 5.6" water pump if you have the KJ KM/KN KG pulley set.

If you have different pulley stampings than mentioned above, let us know as soon as possible, as things may continue downhill from there with even more mismatching of years on your project.

 

Alternator is on the passenger side of the engine.
My issue is that I need to change my water pump pulley to the KM type.
Found one and am going to get it.
I have the one groove pulley now for the power steering, got it from summit (pretty sure this is it) http://www.summitracing.com/parts/rnb-300-122/overview/
Turns out this is not to big of a deal, I noticed the weep hole on the front seal of my water pump is leaking, so I will be swapping it out while I am getting these pulleys lined up right.

 

That doesn't have a keyway slot from what I see. So hopefully your 76 pump isn't keyed.

 

One groove pulley went on pump fine. Got it earlier today

 

I looked up the KM pulley(link below) and found that it says it needs to go on the 5.95" water pump not the 5.6" listed above....which ones is correct?

http://www.ebay.com/itm/1968-72-442-...a08083&vxp=mtr

 

I don't think the 5.95 pump was issued until 1971, so I will stick with my original 5.6 statement.

Openly disagreeing with the company/person selling these pulleys.

 

Thanks for the response...keep in mind the 455 that is in my cutlass is from 1971.

I just want to make sure I get the correct pump to make this work when I do the swap.

Also be sure to check the spacing on your current 2 groove crank pulley.

Some of them are .625" from the balancer to the center of the rear most groove, and some of them are 1.25"

You should have the 1.25. If not, it's from a mid 60's engine, and it's the wrong one.

I wish things weren't so complicated, but if it makes you feel any better, mopars and fords are just as confusing in my opinion.

Chevys are easy. long one or short one. Chocolate or vanilla

 

Although that may be, your 69 cutlass won't be able to tell the difference between the year stampings on your block.

If you still had the factory correct items along with your 69, you could have just tossed everything from the 71 block in the trash can, bolted on your 69 stuff and never skipped a beat.

The year doesn't make a lick of difference as far as the 68-72 455 engine blocks go.

 

Hope this helps, and good luck. 3 out of 4 times, If you swap out 1 card from your royal flush, you're left with a whole bunch of nothing

 

Good to know.

I wish I had all the 69 stuff, when I got my cutlass it had a chevy 350 engine in it. I took all that out and got this '71 455 to go in the car.

I have the KM pulley on order now and will check it on the pump that it still on the motor now and will let you all know how it goes.

Thanks for the help

 

Check out the screenshot I got from Rockauto - i think i am going to get the one with the red arrow. 5.6"

 

Pics of Engine as it is now. I think when i get the double groove pulley on the water pump this will be resolved.
