Default Power steering pump misaligned after engine swap

Hey all,
I recently replaced my engine - block is lined up to engine mounts, also replaced the harmonic balancer - installed fully seated with tool. Just re-installed my power steering pump and it is not perfectly aligned to the crankcase pulley - per the pictures it is angled a little back from where it should be. So looking for some advice wondering if I need to:
1) Bend the power steering pump mounting bracket that connects into the engine mount a little more towards the front of the engine
2) Check that the crankcase pulley is fully seated against the balancer
3) Put a few washers behind the lower bracket that holds the power steering pump between the mounting bracket that connects into the engine mount and the bracket that holds the power steering pump to move it out a nudge - I don't think there were any there.
Would appreciate any thoughts
Bernie

Measure the distance from the dampener to the engine block and see if it is within spec before doing anything. This should be a standard measurement.

I don't have the correct measurement but I am sure someone will have this. If this is in place then proceed to other options.

One other option is check if the PS pulley is pressed / pushed on more than it should. Is the pully flush with the shaft ?

Thanks for the input - just as an FYI the dampener is a new one that is smaller than the stock one (width) so the measurement might be different but if I could have that measurement I can adjust for it

The PS pulley does not appear to be adjustable and it came off as a unit and was put back on that way.

Perhaps get the waterpump on and see how that lines up first. Shimming the pump out with washers at the 2 block bolts and equal amount at the third bracket bolt will move it outward. I have washers on mine. had to when I changed the pump.

Ok cool - I think one washer in each of the spots you mention would do it - just didn't want to commit heresy by doing but feel better if someone else has gone that route

One other quick FYI - I marked the point where the dampener would be fully seated with a sharpie before I installed it and it is right up the that line so it is in the right place

I would still get that waterpump on first and check the belt alignment to the waterpump pulley before I shimed anything. No point in doing it twice.

Why is your Harmonic Damper thinner? Do you have the correct one on the engine?

Before you off doing a bunch of extra work pull off that harmonic balancer. Put the old one one. If it lines up then you know where your problem lies.

Harmonic balancer is same weight just smaller overall profile - double checked with supplier that it was the right one and it also matches other options online from other suppliers - water pump is on and pulleys line up perfectly to balancer - I am thinking I may have bent the bracket for the power steering pump a little getting the old engine out

Could be. easy enough to shim it out with washers and no one will ever notice.

Easy enough. Bend it back, and if necessary to weld and/or brace it ---now is the time to do that. If you can avoid shims & washers you will be better without extraneous material, and it will be easier for future maintenance.

This is VERY common.......something about the position of the mounting holes. My 406 is a GM block and I had the same exact thing happen. Shim it and move on.....it is not the damper or anything else.

It's really not a thing. V belts will work with a much more pronounced misalignment than you have.
Does it work ok?
Shim it if you like, but I'll bet it will work just fine as is.
