Theres at least 3 different single groove PS pulleys, all different offsets . I can see right off that the one he sent you is the wrong offset. Is there a GM part number in this new pulley ?

6066 I must be slow because I don't see the part number you gave me, Can you give it to me again?

6066 thank you I have copied and posted the photos of the pulley you have suggested here in this post, I have bid on the pulley so we will see if I am able to get it. Also as a side note I called Allen grove components again this morning to canceled the order I placed last night and talked to him some more about my problem with the pulley alignment and gave him the part number you gave me he says he has that part in stock but doesn't believe that is will fix my problem. Well see I will post when I receive / or win the pulley and install it on my truck. I am keeping my finger crossed and hope this fixes my pulley problem.......Thank you all for your input. I also noticed that woogo posted this in the FAQ for those who will have this problem in the future.


As a side note for all reading this is the correct GM PART NUMBER 3791943 FOR FACTORY AIR WITH CAST IRON PULLEY. PER 60-66

I just went through this with a 327/air/ac/ps truck, had to add a 1/4 spacer to bring crank pulleys out to line up...water pump pulley couldnt go on more or itd rub the water pump housing. PS was slightly off but just came back from around 500 mile trip and no problems. Never did see if it was balancer or new.timing set that caused the offset. Excuse typos, typjng this on phone.

Didnt see that you fixed it, damnit slow loading phone! Good to see you got it!
