'69 COPO Camaro Cowl Air Cleaner
 
Last weekend I bought a Camaro from a guy who used to own a documented RS COPO years ago. He had installed the original cowl induction air cleaner from the COPO on the car I purchased, and I'd like to understand exactly what I have. It appears to be an assembly line correct flat-bottom base with an incorrect chromed open element air cleaner lid, but with the correct hood sealing flange. Obviously it's a major bummer that the snorkel was hacked but I'm guessing that can be replaced by someone who knows what he's doing.

The decal was a new repop, something the previous owner installed a couple years ago.

Any advice would be much appreciated!

Neat piece! Sorry I can’t add any comments... but I’d sure like to hear more about the Camaro you bought!

In production, L34, L35, L78 & both COPOs used the #6485235 air cleaner assembly. Also used on Z/28 with an extension not used on 396/427. So it is not particularly rare.

Sometime after July '69, the base was revised with a bead to raise the lid for better air flow. Some cars built after that time have the revised base. GMPD serviced the 2nd design #6485235 well into the '80s with another revision; a vent tube with 2 45º bends to clear a Holley double-pumper. GMPD also serviced the seal flange but mostly the version used on Chevelles, notched to clear a vacuum pod used on A/C cars.

Your unit has an original flange. The flat-bottom base is a plus but needs a little work and a lid as noted and is rusty. I suspect that isn't the original seal. Were it complete and in excellent original condition, it would be a great find.

Working against you, the flat bottom ZL2 air cleaner, lid, flange and seal are nicely reproduced for about $250.

Does the rubber seal seam have tape on it?
If so,please show it close up & from different angles..

Not to start an argument but I believe the raised bead on the floor of the base is for improved sealing.
I cannot see how that would improve airflow.
Granted the repop is nice but its still a repop.

Does the bottom side of the lid have the silk screening?

scuncio 03-29-2018 01:43 AM

Thanks everyone, very helpful. No one is hurting my feelings with candid commentary - I will be looking to sell this to recoup some $ from the car purchase so I’m trying to understand if it’s more sensible to sell it as-is or pay to have it restored.

Steve - yes, the underside of the lid does have the original silk screening.

I believe under certain conditions there was an air flow restriction with the original flat-bottom. Elevating the lid would eliminate the problem.

I have had several flat bottoms and the element sealed to the base just fine.

Restore it. Base looks really solid. You already have a line on a snorkle. You have the most important part and having the tube is a big big plus.

scuncio 03-29-2018 04:04 AM

Appreciate the feedback guys. The base is in excellent shape save the obvious snorkel hack job.

William 03-29-2018 05:54 PM

I had a snorkel replaced on a 350/auto ducted hood air cleaner. Very simple repair.

Don't sandblast the rust. Use a de-rusting solution.

'69 COPO Camaro Cowl Air Cleaner
 
My take on the revised bottom of the air cleaner (raised ridge) was to elevate the air cleaner element off the bottom of the base to prevent any rainwater or snow from damaging the element. The Oldsmobile AOI air cleaner also has a ridge for that same reason.

Thanks, interesting idea.

Mr70 04-01-2018 07:29 PM

Tony
Do you have a piece of tape sealing the two rubber ends together?
Pic?

scuncio 04-01-2018 08:52 PM

Rick, sorry, there is no tape on the ends. I can get a picture if you’re still interested.

Mr70 04-01-2018 10:23 PM

Ok,not necessary,thanks.

JBALL 04-02-2018 12:42 AM

Nice piece Tony

scuncio 04-03-2018 12:04 AM

Thanks guys, any thoughts on value before I list it for sale?

scuncio 04-06-2018 02:14 AM

Is $500 out of touch for this piece?
