1970 LS-6 Closed Element Air Cleaner

[Mr70]

Not referring to this particular ebay auction discussed here.
This air cleaner style can be homemade by using other air cleaners parts also.I used to have a single snorkle,same length as the dual,that worked very well to make a dual.I stamped "HOMEMADE" on the inside bottom of it,then sold it as a homemade unit for $100.00,& still see some out there today.It is pretty easy to tell if they were homemade.All its parts can be found to make,although they will look homemade,but some don't care,& are honest about that.
As far as the 1970 L78 Chevelle using them,I have never seen that.It was built to early in the model year,then cancelled before the dual snorkle design was released.The Dual snorkle code for the Chevelles was CO on the buildsheet.I would like to see a 1970 Chevelle L78 Buildsheet reflecting that,it if anyone has one.
The LS6 Chevelle was a later produced RPO,& received the dual snorkle sometimes,starting in Spring of 70.
I believe this Dual snorkle design was produced & slated for the Newly designed 1970 Corvette,with the LS6 engine option.Not having anything to do with carburetor noise issues with other cars.This also was why the new low aluminum intake was designed,because of the new 1970 Corvettes BB hood to engine clearance.
The 1970 Corvette RPO LS6 never fruitioned,so the factory used up the already produced Dual Snorkle inventory on the remaining low rise Aluminum intake later built LS6 Chevelles,L78 Camaros,& L78 Novas when possible.

Did all 1970 L78 Camaros have this air cleaner? Was it introduced sometime later into production due to either noise complaints or to eliminate GMs stock pile.

As far as I know all of the 70 L78 Camaro’s built had the Dual Snorkel air cleaner.
That was probably the first thing changed, I know I would have taken that BIG A$$
air cleaner off if I had brought an L78 back in the day. The AIR and exhaust was probably
the second thing that was swapped out. If we only knew then what we know now……
BTW, The air cleaner was a CO code on the Camaro build sheet also..

Mark, Did Norwood cars have a build sheet?

[camarojoe]

All cars had buildsheets, just so happens not many from Norwood left with the cars. They are out there though.

Dual snorkel air cleaners were used on the some later L78 Novas. The latest car I have that I can document the open element on is feb/70. I have a 1st week of july car but it did not come with an air cleaner. The buy it now price of $2600 is more than I paid for my first L78 car in 1974. Wow! How things have changed!!

Well, the seller wrote to me today and said while he was packing it up he noticed one snorkel was attached differently. I still bought it, curious to see what its like when it gets here. Maybe there will be a HOMEMADE stamp after all.

Build sheets are “Extremely Rare” in Norwood built Camaro’s but a few cars
slipped through with them, from what I understand they were very strict
about leaving them in the cars at Norwood….

Rare original 1970 Chevelle unit for an LS6 or L78, twin snorkel type. Has a little pitting in the inside of the housing at the bottom. All together a really nice piece, not brand new, but very showable for most cars. The chrome is excellent on the lid. You won't find too many chances at an item this rare. Also fits a 1970 Camaro with the L78 Thanks for looking and bidding!

Jason with a description like that they had to notice it was put together differently on one side .....

1971 LS-6 Corvettes used an open-element design air cleaner, part #6485239, with a base like the one shown in this attachment. I would think that this part probably would also have been used had there been a '70 LS-6 Corvette. I don't have an assembly manual for the 1970 model to check for any LS-6 cancellation pages, but the LS-5 & LT-1 also used an open-element design, #6485887.
