Stan,

great photos - we can see the LT1 carried the same tube as the earlier 427 bases.

The 71 LS6 has this larger 90 degree bent tube.


One thing some of you might have over looked in those photos from Stephen...alligator skin on the original connecting hose.

Hope everyone picked up Stephen Byrd post yesterday Oct.14th of his 70 350-350 S/N 9638 May 19th photos. That is the tube that I was describing. I know we have a few more of those in this discussion. Just trying to see if they may have been a haphazard install at the factory some cars received the 45 deg tube and most others got the 90 deg. Just food for thought. Stephen Byrd thank you for that addition.

Mine will not be as big as Stanly's. I don't have a photo storage/linkage account.

From my one owner 1970 LT1 #2161. Absolutely positively the one that came with the car:

The last image is for all you fans of agitator hide. That is deterioration and in my book merits a condition deduction. Like the sunken seams and yellowed windshield washer pump outlets, it wasn't that way when the car was new.

Pictures of my 1970 LT-1 air cleaner, I remember the car but not the serial #. I have the TI, intake manifold, carburetor and air cleaner. Just need to find the rest of the car..

IMO, it looks like Terry's..

1970 LT-1 coupe vin #5020 build date February 26, 1970 I cannot confirm this is the original air cleaner bottom, but it came with all of the other parts with the car.

Paul,
Two more photos of my 5 star70 LT-1 #14803. From my earlier post this nipple faces the valve cover and not the firewall.

The 70 was an 18000 mile un-restored car the 69 was restored it seems at this point at any time in 1969 and 70 you could end up with ether style. Pointing 90 deg from center line or 45 deg.
From observing 1971 and later all seem to point 90 deg from center line. We just have to keep observing this to come to some sort of conclusion. Both bases appeared to be originals. Thanks for the photos.

Re: Air Cleaner Base 1970 LT-1

Paul,
Any asy plant would be purchasing one base, based upon option content specifications of that car, not several months prior, or several months later so any flip flop should be look at carefully.

And as often a people like to blame the union for shoddy work, well, they did not ship a completely different part for months on end, nor should we subscribe to the idea they mis installed an entire years' worth of parts.

A "detailed" study of the AIM's, engine options vs, dressing configurations and service books may tell most of the story. There also might be a case of service part consolidation as early as '72 or '73 where a deep dive into the prints would tell us the entire story. Any car could have had the part changed, restored or non restored, and up to this day, with patience, you can still find NOS parts out there to please your restoration.

Then you have to consider that this one is so subtle, for 39 years it got past the best of us.

Gary are you the owner on these two? Interesting fascination with horizontal round wire mesh filters!

Re: Air Cleaner Base 1970 LT-1

Today I had another opportunity to see 2 1970 350-350 bases 1 S/N 1900 something and the other 4300 something sorry about forgetting the VIN. Both pointed at the 45 Deg. See photo below.

Ron I am not criticizing the workers or anything like that all I want to do is add information that from 1969 to 1970 there is a possibility of either base type 90 Deg or 45 Deg. could have been used with an open element air cleaner. At least that is what I have and now all the other member who are now looking at this oddity. From what I have seen at or about the 71 production point they all look to be the 90 Deg setup.

Re: Air Cleaner Base 1970 LT-1

Paul, its management and engineering that caused a situation where two assemblies that are nearly identical were in the same single plant and both could be installed on the same engine. Its not the operators fault at all.

I am sure it it possible, you C3 experts need to pull out the aims for each year, map them and study the 70 71 and 72 parts books. I am certain that the two bases left AC Flint as intended.

Re: Air Cleaner Base 1970 LT-1

You guys will get a chuckle out of this air cleaner base at 45 degrees, a numbers matching 66 big block, its the last picture.

Ron,
I am not certain the filters are original to the cars, but pretty sure the bases are. And to answer your question, no. They are not my cars. Wish they were.

Paul, I agree that we need a statement that says either design is acceptable for 69 and 70.
