CA WTB - 3 Groove Crank Pulley for SBC with Short Water Pump

[pjmoreland]

I've currently got a two-piece two-groove crank pulley setup, and I'm looking to go to three grooves so I can add A/C. I believe I only need a new inner pulley with two grooves to go with my current outer single-groove piece. Please correct me if I'm wrong.

I hope this helps. The part number is 3744043 this is the 2 groove pulley. Still can be purchased thru GM. Can also be purchased on EBay. If you need more help let me know I have this pulley setup on my 72 with factory air. Thanks Don

Thank you! I'll order a new one.

The other pulley #3751232 would be the power steering pulley single groove. That should you there. Don

Do you think my existing single groove crank pulley for my PS will work with the double groove pulley?

Yes, you are on the right track and it should be as simple as swapping the single groove inner crank pulley out for the two groove inner and then reinstalling the outer p/s add on. If working with an OE style swp (LH/drivers side alternator) bracket/pulley setup, what year is your setup, are your existing pulleys OE GM pieces and if so do you know any of your pulley p/n's? Had you mentioned needing the crank pulley, we could have added/combined a swp inner two groove crank pulley (OE used $35.) in with Fridays steering column parts order. Don's above added pulley p/n info looks good for small block 72 models, so if you are going to be buying/chasing the above mentioned 3744043 BA two groove inner crank pulley then you should also have the matching short water pump two groove pulley p/n 3995646 AH (see below). Let us know if we can help with any OE swp pulleys, Mel

Is this also the correct parts for a 68 w/ps and factory air? Short water pump.

The pulleys arrived safely. Thank you for your help.
