1970 dual snorkel air cleaner lid

[Jordan S.]

Does anyone know if there are siginificant differences btwn the noah performance air cleaner lid and original for the late 70-72 dual snorkel assembly? Looking at the picture (http://cgi.ebay.com/ebaymotors/1970-...ayphotohosting), it seems the Noah lid has 4 dimples around the central hole compared with 6 on my original. Is this true? Anyone know of a more correct repro?

Does anyone have an estimate of what it would cost to re-chrome my original?

Thanks.

Hi Jordon,
The lid from my 71, #6589, has the 6 'dimples' you mention. I have a reproduction lid from Paragon that's a very nice lid with 4 'dimples'.
The only variation I can see (besides the dimples) is that the outer most lip's vertical surface, is not as tall as the original. This seems to be because the last tiny roll that's formed in the lip is larger than the roll in the original. The roll in the original is tighter and thus more of the vertical lip's surface is seen. This all occurs on the outer surface of the lid. This is the lip that is formed to hold the round rubber gasket at the lid's outer perimeter.
The chrome plating on the reproduction is much nicer on the reproduction than on the original.
I got a price of $125 for re-plating my lid a few years ago.
Regards,
Alan

Thanks Alan. That's the exact info I was looking for.

Re: 1970 dual snorkel air cleaner lid

I had my original lid replated for $85, but that was +8 years ago...

One note, originals tend to rust/pit in the low spots where water can puddle making it hard to impossible for the platter to polish out the pit once the cover has been de-plated. You wind up with PoP, plate over pit, inconsistencies that most judges can spot for condition deduction(s) despite the fresh shinney new plating.

I'm years away from judging but do you think the condition deduction for plate-over-pitting would be more or less than originality deduction for the re-pop lid?

Re: 1972 dual snorkel air cleaner lid

Searching posts for info regarding 1972 small block 350/200hp engine dual snorkel air cleaner lid.

Reading the post regarding the 1970 lid references 4 center dimples on repro covers for 70 + 71 and 6 dimples on original ones.

Two questions:

1. Did the 1972 small block 350/200 with air use the same chrome lid with 6 dimples?

2. Are there supposed to be silk screen instructions on the underside of this lid (i.e.: with dual snorkel) OR are the silk screen instructions limited to the open air cleaner assemblies only.

Just trying to sort out fact from fiction.

Hi Scott,
I'll try to respond to your 2nd question.
I believe the 'closed' air cleaners had a rectangular information sticker on the left vertical side of the base instead of the silk screened instructions of the earlier open air cleaners.
I've included a link to a post that shows some of the repro stickers that are available and their slight differences.
I believe Patrick Hulst has some pictures of the sticker from his 72 BowTie car on his picture link at his profile page.

Here is an original decal from a very late 71 ZQ3 Bowtie car.

Re: 1970 dual snorkel air cleaner lid

I believe that the 70-72 Corvette (exc. SHP)("CR" and "6485887" on white sticker) and the 70-72 Camaro SS350 use the same 15 1/2" chrome air cleaner lid.
I have 5 original 70-72 Camaro SS350 air cleaner assemblies w/chrome lids. The bases all have the white sticker with "CK" and "6485242". Two chrome lids have 4 "dimples" (photo below), two do not have any "dimples", and one has 6 "dimples".

I also have 2 black painted lids from 70-72 Camaros w/307 eng. Both of these lids have 4 "dimples" and are identical to those mentioned above except for being painted. My black painted lids are in very good condition WITHOUT ant pitting. My plan is to have these lids chrome plated. I do NOT buy repro parts.

There has been some discussion about these lids and the number of "dimples" on the Nasty Z28 website as listed below.

You will be very disappointed in the NOAH product.

In fact, he will probably tell you he won't sell to you if you are looking for a NCRS type piece.

Been there done that including the conversation.

They are good pieces to look at from 20 feet away, car shows at the strip mall etc. They are not intended to have all the fine details you are looking for and he is very up front about this.

Re: 1970 dual snorkel air cleaner lid

My suggestion for those who want an original 70-72 lid is to find find a black painted "generally flat" lid from a 70-72 Camaro,Chevelle, or Nova w/307 or 350 w/2BC. They are quite common at swap meets. For some reason the black painted lid are generally in much better condition than the chrome plated lids. Both of my black painted lids are in very good condition WITHOUT any pits.
All seven of my original lids measure 15 1/2" in diameter. The repros by Paragon and Corvette Central list the diameter at 15 5/8".
