air cleaner for a 1969 L72 427

What is the correct air cleaner for a 1969 L72 427 engine?

Is it this one? Does anyone have a part number for it?

note: this picture is from the 3rd message down at this link: Original 69 Yenko

Are reproductions available?

The 1969 Factory Assembly Instruction Manual lists (on UPC 6, C8) the Air Cleaner as number 6484597 but I cannot find this number anywhere else.

I have seen some places list GM number 6485891 as the correct air cleaner like this Ebay auction:
427 Air Cleaner listed on EBay

I am thoroughly confused.

Does anyone have any info on the Camaro 427 air cleaner?

Dave, The air cleaner you listed (6484597) is for a two barrel small block. You have to flip to the end of the Assembly Manual, page 483. I am assuming you're looking for a Cowl Induction air cleaner by the eBay link you posted. The big block ZL2 air cleaner is the same as the small block air cleaner with the only difference being the small block air cleaner uses a spacer to make up the height difference.

Bill, I have a 1969 Camaro.

Joe, Thanks, page 483 makes things much clearer! Actually I am not looking for a Cowl Induction cleaner. I have been making myself nuts trying to figure out what is the correct air cleaner for a 1969 Camaro with a 427. So I don't need a ZL2 then and I am totally looking at the wrong air cleaner! Which page is for non-cowl induction?

ummm ... the 427 never came in a Camaro without the cowl hood

the 396 did, but you had to use the SS hood ... the SS 396's without the cowl hood used the open element air cleaner that all hi perf Chevys used ...

Since you're not looking for a cowl induction air cleaner, I think your car might use an open element air cleaner. Have to do a little researching.

Sorry for my confusion, but would all 1969 Yenko Camaros have a cowl induction air cleaner?

Yes.

Thank you Wayne. Then I am looking for a ZL2 and I should figure out page 483 of the Factory Assembly Manual. Are there any other books (perhaps a restoration book) that might make it a little clearer on what the different parts are? I think I have a lot to learn. What is a L48, M35, M38, etc.. I tried a few RPO decoders on the net and the answers do not make sense.
