Air Cleaner Base 1970 LT-1

[Paul O.]

Any one with a 1970 LT-1 does the passenger side vent tube to valve cover for your air cleaner base point toward the firewall/heater-box or toward the valve cover. Would help to know if for early, mid or late build would help and if it is a know original also. Have just noticed that 71 and later LT-1 tubes may be aligned differently then a 70.

Photos would be great if you have them.

Added photos 1st showing 1970 tube direction then 2nd 1971.

Added 3rd photo hoping better the 1st 1970.

Paul,
Attached is 71 LT-1 #16798. Just like yours. I have about 500 photos of my 70 LT-1 #14803 but none with the air cleaner on the car. I will take one and post it later today.

Paul,

I have a 70 lt-1 air cleaner that in V/G condition and it is like the picture Keith posted. I would say the breather tube points to the firewall/heater box instead of the valve cover and the rubber hose attaches like your third picture.

Re: Air Cleaner Base 1970 LT-1

The ONLY difference 67 - 72 is the orientation of the tube. This being those with one tube exiting the 5 o'clock position. Known originals, original owner, etc. will be required to establish a trend, especially if it is as it appears that the tube could be in both positions and the car built.

What does the 70 LT1 resident have to say???

I don't know who you are referring to Ron.

My 1970 is temporarily unavailable, and my photo files at all F*&^(@ up as a result of a virus. They exist on the computer, but I have a very hard time getting to them. It is usually easier to go and retake the pictures, but not at the moment in this case. I'll get there eventually, but Paul didn't want to base a conclusion on my one car anyway.

This is one of those things that when Paul asked me I said -- I just never noticed. When judging the owners usually have the air cleaner assembly removed from the car when we approach -- so it is a detail easily overlooked.

Re: Air Cleaner Base 1970 LT-1

As many LT-1's as I have looked at, I cannot recall seeing one configured like you are showing Paul. But what do I know. I have only been to three world fairs and two goat roping's

As Terry stated at most times in judging the air cleaner has already be removed and this would be less noticeable. I have now viewed about 20 70 LT-1 photos and it is about half and half. But I do not know if they are all originals.

The reason I posed this Question is this past weekend I viewed a members 70 LT-1 and he posed the question to me. He has 2 70 LT-1 around S/N 7400 both the same configuration I did not have an answer. I would also expect it on a 350-350 or 327-350 engines 68 69 and 70.

If there is a position change for this tube on the base I just trying to see if there some time frame for this. Plus give the owner a good answer.

Also the second photo is of my old 71 LT-1 I was second owner from 1974 and the base is the original one S/N 1914 so an early 71 also have many other 71 and 72 know original in the configuration as mine is.

Although My car has been through 4 owners before me, I feel confident this is the original breather. Other than headers in year 2 the only things changed on it were maintanance items.

Paul,

Sure looks like your '71 photo, Dave Strickland's '71 picture and Keith Lutz's first '70 photo all look to have the tube pointing toward the rocker arm cover instead of the firewall. Which position does the owners 2 '70 LT-1's face?

Re: Air Cleaner Base 1970 LT-1

Would the 1970 LT-1 base be the same as the 1969 Camaro Z-28 base?

Scott, I would think that it should be, but who knows.

Re: Air Cleaner Base 1970 LT-1

And I was wondering if the base might be the same as the 1971 Corvette LS6 -- but we should probably confine our survey to the more common application first before we open another can of worms.

They pointed to the firewall/heater box.

Also Warren the car I viewed had that little hole below the screw hole on the drivers side for the coil bracket. Right below where the screw head is located.
