250 P/S Crank Pulley?
I need help identifying a part. I have this single pulley,#3790337BE,and I'm pretty sure it's the crank pulley for a 250 w/ power steering,but want to confirm. Would it be P/S without A/C? I'm just not that familiar with 250 stuff.

Re: 250 P/S Crank Pulley?
That pulley looks like the a/c pulley for I6 applications. Mine has a different number.... If memory is correct, the setup I have, that pulley drove the a/c pump with the closest to the block turning the p/s pump and the middle turning the alternator
Pic "borrowe" from RichardJ....292 setup but same pulley config: And here is what I have off of a 250 79 Nova: |

In my best Vinnie Barbarino voice,I'm so confused!!!"
I would have agreed with the 6 cyl A/C response but now I think the later reply is closer.GM didn't make a new "widget" if one they already made would work.

Re: 250 P/S Crank Pulley?
Thanks Mel and all for the info. I guess it's what I thought it was and much much more!
 I was hunting for a small block,short pump,P/S,no A/C pulley and thought this was it. But,I looked up what I needed and found that was #3755820BC,which I had. What raised a flag is the center whole is larger on this one. There are other differences (offset) now that I have them side by side
