68 z smog system
« on: September 27, 2012, 06:16:07 PM »
Have a smog system from a 1968 z28. Taken off by the original owner in 1968 w less than 500 miles . Sitting in his attic for 44 years until last month. has a shallow groove pulley,nothing is altered,modified or ever changed. I have read that others[including one person that took it off when new] have seen this,was there a time frame when it may have happened?  Pics to follow

Thanks for the info,I would have thought a 522 pulley but knew where this came from since new. Maybe it was a late in the year thing as 3 people have June cars[approx] with shallow groove pulleys on them  .

My pump is a June pump but the car is a 07C.  Being the smog equipment was added on the engine dress line at the car factory, the July date would be be the closest common date.  Do you know what week your donor car was produced?  BTW....got a photo of the pulley face?
