    I'm looking for some help on the pulley alignment regarding the power steering pump. I am finally installing A/C and want to know if the rear groove on the double groove p/s pulley is supposed to line up with the rearmost groove of the crank pulley. My crank pulley has one large groove on the front side and the two behind it are the same size. My car was an original A/C car but when I bought it, it didn't even have an engine, so I'm flying blind here.

    Yeah. Rear-most groove on the PS pump goes to the rear-most groove on the crank.

    Ok...I had a used 2 groove p/s pulley and a used 3 groove crank pulley a friend gave me. I pressed on the p/s pulley and bolted up the crank, but the p/s pulley only lines up with the front two grooves. It won't press on anymore. Any idea why?

    Can anyone post a photo of their pulley setup with belt routing with the A/C comp on the driver side? And does anyone know if the aftermarket Saginaw pulley that is available from summit would work?

    I think it would be more helpful if you posted up a pic of what you've got. Lining up with the front two grooves on the crank pulley doesn't sound right at all. Front groove is ALWAYS for the Alt & WP on a v-belt SBC car. I've seen no exception to that rule.

    I will, once I get a new p/s pump pulley. I bent the hub on mine trying to press it on further. :/

    If it's a later model pump (no retaining nut on the front) the pulley should press on until it's flush with the front of the pump's input snout.
