Re: Air Cleaner Lid

James, I would check on ebay and look for seller John Miessinger (sp). He seems to have them listed quite often. As for labels, Paul Noble may have what you need.

Re: Air Cleaner Lid

Geeze, Louise, isn't that car done yet, James?

Here's my two cents: don't touch the underside of that factory original 396 air cleaner lid. Just, clean up and re-spray the upper surface. We see so FEW factory original 396 air cleaners that the odds are pretty good your Mech judges will develop tears in their eyes when they see the 'real deal' item that their vision will distort to the point of NOT seeing the condition wear/tear on the underside of the lid...

That's my experience from having campaigned my uncle's 396 on the Duntov, Bloomington Gold, and Triple Crown circuits. I don't remember any condition deductions other than stray comments here/there (without points being taken) and MANY 'smiley face' annotations!

Re: Air Cleaner Lid

One thing thats obvious on a show chrome lid is that it's noticeably heavier when compared to an original...

I agree that there are very few unrestored 396 lids with the original silk screen, rack marks. I have seen fewer that still have the original embossed labels!

Attached is another example of an original lid from my '69.

Re: Air Cleaner Lid

Jeff,
I have an original air cleaner assembly from a 1969 Corvette (at least I believe so) that I purchased in the Fall of 1979 and the silk screen instructions on the bottom side of the chrome cover are "straight" like yours. My original 1966 Corvette air cleaner cover has the "curved" silk screen instructions.

Re: Air Cleaner Lid

Dave,
I believe the silk screen instructions changed from curved to straight during the 1969 model year, so one needs to identify when during the 1969 model year the car was built.

Re: Air Cleaner Lid

My car is October '68 (5854).

Re: Air Cleaner Lid

Terry,
I think you may be right. I have noticed that Paragon's reproduction chrome cover with the "curved" silk screen instructions is sold as a 1966-1969 cover. Maybe the extended production run (to Dec. 1969, I believe) for the 1969 Corvette had something to do with having both types of instructions.

David that is what I would have thought -- except for Jeffrey's example. Like usual we need more data points.

Re: Air Cleaner Lid

The 69 Corvette 350 (exc. SHP) and the 69 Z28 (1st design) used air cleaner assembly # 6423272. The 69 Corvette 350 w/SHP and the 69 Z28 (2nd design) used air cleaner assembly # 6423907. I assume the same chrome cover was used and something was different about the base.
Jeff, is your 69 Corvette a 350 w/SHP or not?

[Jeffrey S.]

Re: Air Cleaner Lid

My '69 is a base engine 350/300hp car.

Re: Air Cleaner Lid

Jeff, Dave, at the end of this thread it switched to the 69's, and these two air cleaner assemblies:

6423272 69 Corvette 350 w/SHP

6423907 69 Z28 (2nd design)

My parts book only has the Corvette, do you know what lid/filter/base differences were for these?

And was 68 the initial release of these part numbers?

thanks,

Re: Air Cleaner Lid

From a Corvette 74 parts book:

65-67,396,427, 68, 69-72 w/ SHP 350 all used the 6422188 base.

This base should have the vent tube larger and exiting the RH side.

66-67 except 427 used base # 6422931, it also references w/ 6421816-2286-3240-3907 and that string of numbers must mean (?) that this 327 base was used in those 4 assemblies ending in 1816-2286-3240-3907.

This base should have the smaller vent tube exiting the LH side. And in reality somewhat rare as a two year part. Were there differences between 66 & 67?

Re: Air Cleaner Lid

Ron,
FYI
Base # 6423910 was replaced with base # 6422188 in Nov. 1968 as per Chevrolet Parts History.
Base # 6423910 was used on the 67 CORVETTE w/H.D. (427) as per my 1967 Chevrolet Parts Catalog (Apr. 67) in Gr. 3.406.
