68 Z28 open element air cleaner

[68Zproject]

If you don't mind could you ask him if that kit listed in the other thread with the base, filter and lid has this same lid that's correct?  I'm going to keep my base and need a filter so I thought about getting the whole thing and parting out the base in it.

Well, that's the one, but note that this is a CORVETTE part, not Camaro. I say that because per the AIM's, the 68-69 Corvette used P/N 6423272 Air Cleaner Assembly, but the 68-69 Camaro used P/N 6423907 Air Cleaner Assembly. Two different parts. Note the differences in the arrestor pipe orientation on the bottom of the bases (see picture below). The base that comes with the Paragon assembly is P/N 2091 and has the orientation like my "Corvette" base in the picture.

I think the list that Kurt posted had the 68-69 z's using the 3272 and the 67's show the 3907 and the 68-69 big blocks too.  Either way, the base they show at Paragon isn't correct for my car as it looks like the corvette.  I don't know how it could be the same part # although that doesn't mean much these days with parts suppliers.

Per the AIM's, the Z28 went through a few changes! In 1967 it was P/N 6423907. Then in 1968, per note 5 dated 11-27-67, it started out with the 6423272, then went to the 6423907. Then in 1969, per note 1 dated 6-30-68, it went from the 6423907 BACK to the 6423272!! Jeez, can't Chevy make up their freekin' minds???

No they can't and I don't remember if you had a late car too, but there's a lot of things that got put on cars in the 5 range like mine that got some left over 67 parts.  I remember I freaked out once looking at steering arm numbers or something like that thinking someone had changed all these parts until I read about GM using up inventory to finish cars toward the end of the model year.

I wonder if that is sometimes the case for these things like the air cleaners.  They obviously would fit any of the Z28's any year so what's a part #?  Same thing for the straight vs curved lettering on the lids.  Without decisive evidence on the lettering, I would speculate so far that supply and leftovers could be the reason for no definitive pattern on some items. 

The only way to know for sure what was on my car would be to go back in time and watch it being made on the factory floor which is about as likely as me finding a distributor and fan clutch at a reasonable price for my car.

Is there a difference in negative hieght?  Distance from bottom where element sits to th carb flange?

[68Zproject]

See reply 9 and 10.  I'm not sure it's been decided 100% though.  I personally would like to see a more definitive answer for original bases for the 68 z28.

I finally got a chance to measure them and yes, they are a bit different. VERY difficult to measure, but it appears the Camaro is 2" and the Corvette is 2.125". That may not be exact since I used a tape measure and not a caliper (mine broke a few weeks ago), but you can definitely see the difference, even with the tape measure.

Thx ed I will measure mine and share the results, but even then I don't know if mine is oem or repop? So it won't mean much.

If we're measuring the same, I get 2" also.  I measured from the bottom of the base to the bottom of the carb flange.  IE, upside down from the bottom to the bottom.

Yes, that sounds right.

Jerry said that Paragon has an exact reproduction lid that's acceptable for Concours judging and has the GM silk screening. I can't find the part on their site (all they show are the triple chrome lids), but the part number for the "assembly" with the flash chrome lid is 8513K. I'll check Jerry and see if he knows just the lid part number.

Ed

That's been a excellent repro for sure. Part#6423272 is what I have listed in my files from what Jerry or possibly JohnZ had stated some years past.

Part # 1756 is the lid only.  That's the flash chrome as original with silk screen instructions.

Maybe I'll just get the lid re-screened.  It looks like my base can't be proven to not be original and one of the two lids would be acceptable.  I also found an original cw212 air filter I bought years ago that looks just like the one they sell.  It's mesh and not the soldered wire, but I haven't seen anyone that sells a soldered wire diagonal one like should be on the 68.  Even the "survivor that tx302 was looking at on epay was a mesh and it didn't even have the white silkscreen like mine.  I guess that's as good as it can get for now.
