When I bought my 63 roadster it came with a bunch of extra parts. Among those was the power steering ram, cylinder, hoses and drag link assembly. I have rebuilt all of that and thought all I have to do now is get a ps pump and bracket.
I ordered a new bracket set for 327 from Zip. Got a Lares pump from Rock Auto. I had a pulley on the shelf. Put it all together and the pulley is too far forward. The engine in the car currently is a 350. But that shouldn’t matter, right? It had a two groove crank pulley and wp pulley. The alt is on the pass side and uses the outer (fan side) groove. The inner (engine side) groove is empty.
The new PS pulley lines up in front of the outer groove so I ordered a 3 groove crank pulley and a three groove water pump pulley thinking that would fix it. But the water pump pulley won’t bolt up to the pump!!!
My question is… do I look for a three groove water pump pulley that will fit or is there a special ps pulley that will mount closer to the ps pump so it will line up with the inside groove?
I swear I can make the most simple things so complicated.
My hunch is that you've got the wrong pulley on the PS pump.
The factory set up, and you probably know this, used the stock 2-groove crank pulley with an auxiliary pulley bolted to it to provide PS pump drive. So with the right PS pump pulley, you should get proper alignment with a factory PS crank pulley.

Post pictures if you can.
So with an added pulley to the crank you effectively have a three groove crank pulley. What went on the other grooves besides the alt and PS? Also what about another groove for the wp? In the stock setup (I know 63 didn’t come with ps) which groove did the ps utilize?

The factory set up for 250 and 300 engines used 2-groove crank pulley and 2-groove WP pulley, but only a single belt which went around those two and the alternator pulley. PS required the addition of the bolt-on third groove for the belt which drove the PS pump.
I see that you have an aftermarket crank pulley. I think you would be well served by purchasing repro or original '63 crank pulley (get the narrow groove version, not the deep groove version used on solid lifter engines) and the repro or original bolt-on PS pulley. Then see where you are with respect to alignment with the PS pump pulley.
Also, if you don't have the stock, original, narrow, 2-groove WP pulley, consider getting that also.

you could definitely buy 63 Corvette with power steering yours may not have come with it but it was available. You just need the third pulley that’s available at most places like zip Corvette.

It looks like they are out of stock at most places. You will also have to run the factory 2 belt pulley on the crankshaft. I have an extra add on pulley on the shelf for $40 plus shipping from 19044.

So if I’m reading this correct you’re saying that the additional crank pulley added another groove to the fan/radiator side of the pulley that the power steering pump ran off of. But did it just run from the crank to the power steering pump or did it also run around the water pump pulley?
If so then how many grooves were on the water pump pulley?
I hate to ask so many questions but when I look at paying $130 for a March Products water pump pulley and another $50-60 for other pulleys trying to find the right combination only to find out that it doesn’t do what I need it to do it starts to get expensive and time consuming.
It looks like to me that this add on pulley just adds an additional groove to the radiator side of the crank. That would line up with my new PS pulley but is it supposed to go around the water pump pulley also? If so then the stock 2 groove WP pulley will not work since the radiator side groove would not be forward enough.
Or does the PS just run off the crank and no other pulley?
The bolt-on extra crank pulley drives only the PS pump. Nothing else.
The crank pulley and WP pulley both have two grooves. The rear grooves on both are empty. The alternator belt goes around the forward WP pulley groove and the forward crank pulley groove.
I do understand how costs add up rapidly if not using stock components. One advantage of using original or repop parts is that you know everything will fit and work. Another is that you end up purchasing only one set of parts.
On the built 350 currently in my 63, I run an underdrive 3-row crank pulley, with a captive water pump belt in the (rear) inner groove (where the factory L76 idler belt ran), a WP & alternator belt in the middle groove, and a dedicated PS belt in the outer groove. It's not stock (my original engine in storage has the factory pulleys), and I use 2-row pulleys on the Alt & PS pump for belt alignment, but it does not throw belts during +7500 rpm shifts.

Adding PS to the 63. Need help.
