Although that description say either keyway or press-on, if you check on billet specialties site it'll be for a long pump, press-on shaft NOT a keyed shaft pump.
(just went through a tone of pulley info looking to replace my double with a single pulley)

86120 is the single keyed shaft pulley, can't tell you if it lines up on a SB

Seems to be hard to find a pulley for a short pump and without ac, the most ones are to the ones with ac and they doesn't look the same..
Maybe I should get it powdercoated in aluminum color instead

If you go to Marchs site you can see what they offer for offset dimensions on their various pulleys

http://marchperformance.com/accessor...g-pulleys.html

but without changing the WP pulley and maybe brackets you may find it hard to match up.

Speedway also sells a single groove, 5/8 keyed short water pump pulley, part number 91032916, check the dimensions for the offset

I did find a deep single groove PS pulley (steel) that allowed me to change from the cast 2 groove to a single but that's not likely what you're after

Just looked up the deep groove pulley part number from my notes on my power steering pump:
Power steering pulley (deep)(GM)
3834720

This is a key slotted pulley. As cheap as 60 bucks on ebay as of the date of this post.

Does your pump shaft have a key/keyway?

You can see it, as installed, here:

I think that's what he already has and he's looking to change it to something better looking. I could be taking it totally wrong though in which case the info I gave is more useless than normal

Yeah, I'm a bit confused ....but as long as I did the research... it looks like the 1974 SBC Corvette PS Pulley was 3770509 per this reference:

You could polish yours with sanding discs to a smooth finish then apply primer and paint or all in one primer paint. It's not a bad looking three spoke design IMO.
These 3M sanding roloc discs make short work of it.


Brake cleaner and de-lint prior to shooting.

This is good>>>



This is not>>>
