Coy....I went ahead and bought the 5 of the #336793 in Denver.  I called Aztec Chevrolet back and had him recheck and he said that they still didn't show that they have the studs.  He did say that they were in the middle of a complete parts re-inventory and call back in about a week and maybe they would show up.  Oh well! 
Thanks again,

Yeah.....I looked at that pulley chart and I also read Jerry's book and they both state that it should be a #3925522 pulley but like I said.....this system has never been touched so I'm fairly sure that it came from the factory that way.  I guess I will just leave it the way it came.  Thanks,

Coy.....I called the Aztec Chevrolet and he said that they didn't show any but I called my local Chevy dealer and he said the he found a package of 5 in Denver, Colorado.  Does your parts locater show that same info?  BTW....thanks a bunch for putting me onto the number,

Yeah Coy....I looked it up in a 1976 and 1981 parts manual and that is exactly what I saw.  Thanks for the info.

Restoration / 68 Z28 Smog Pump Pulley

« on: December 18, 2008, 08:48:06 PM »

Question for all the experts.....I have an original 68 Z28 (engine build date of June 19, 1968) that has a smog system that has never been touched, although it has been sitting on a shelf for the last 25 years.  Now that I have decided to restore the car back to original, I have been cleaning up the smog system to reinstall it.  I had always thought and seen nearly everywhere that the 68 Z28 smog pump was supposed to have the deep groove #3925522 pulley, but mine has the #3927116 pulley.  I looked up the setup in the 68 Assembly Manual and under the RPO Z28 section nothing is mentioned about having a different pulley other than what comes standard on all the other V8's with manual transmission and no air conditioner, which is the #3927116 pulley.  I looked up the parts manual and it stated the #3925522 pulley was for the 68 396/427 HI Po engines but nothing was mentioned about the 68 302 having anything different other than the #3927116 pulley.  Am I missing something here?  Could someone possibly tell me why this discrepancy is present in my system or is it actually standard for the #3927116 to be present?

Thanks in advance for any info.......

Restoration / 1968 Z28 Water Pump Studs

« on: December 18, 2008, 06:45:08 PM »

I have a good RH water pump stud but I don't have a LH stud.  My alternator bracket is just bolted to the water pump with a bolt and the bracket appears to be spaced to far in toward the block when you look at the adjust bolt connection at the top of the alternator...the outside bracket kicks out at the end of the two brackets.  It appears that there should be a stud there instead of a bolt.  Does anyone have a good number for the correct stud that would fit there?  I can't seem to find any part number in any of the books and manuals that I have.  Any info would be greatly appreciated. Thanks in advance,
Sonet
