1970 chevelle air cleaner

I am currently in a discuss with a friend pertaining to a what I think is a correct air cleaner that I am having restored currently.
My research for the base of the system shows that there is only one style for the L34 (single snorkle style, not considering duel snorkle or open element). My understanding is that the correct base should have the "production ripples at the bottom" not like the repops that do not have this shape. We agree on that, but he is under the impression that there is a correct second design (which is more rare according to him ?) where the upper lip or flange seat of the base is flat unlike mine where it is flanged out appr. 1/4 inch around the diameter ( above single snorkle). Question #1 Is there two styles for chevelle single snorkle? Heard the term "Flat bottom" but dont know what it refers too. Question #2 What is valve of restored correct breather? -blasted, correctly painted, not dented.

Reason I ask is a couple of months ago I was bidding on a breather on ebay that needed restored and lost at the last second with a bid of $710

#1) I'm no expert, but, I suspect there may only be one 4BBL, single snorkel, non cowl induction air cleaner in 1970, only one will have the correctly coded GM decal, for a 1970 Chevelle w/L-34 engine, w/o cowl induction.
..... "my 1970 El camino w/350, has a 15 1/2" inch diameter black lid, w/11" snorkel snout" ...

#2) I have idea what the value of a correctly restored 1970 single snorkel air cleaner, is ...

If you have the build sheet, post the code from the box marked #55 Air Cleaner.

The L78 came with a Holley carb, while the L34 came with a Q-Jet.

However, even though very similar there were two different varieties used.
The difference is in the bases of 1970 models and the 1971 & 1972 versions.

In 1970 the air cleaner has a large base with a single snorkel. The snorkel is tapered, smooth an un-interupted unit. The base also has a crankcase vent tube.

The 1971 & 1972 air cleaner is almost identical with the exception of the snorkel and two appendages on the base of the cleaner. These extra features make up the thermostatically controlled air cleaner, and were not used on the 1970 model year. So......if you have a 1971 or 1972 with cowl induction and want to be correct the air cleaner must have the "thermostatic components" on it to be correct.

Make sure you use the correct black wing nut, with the black air cleaner lid if you have Cowl Induction.

I believe there may have been variations on application of chrome/black and a different dual snorkel air cleaner in 1971-1972.

I agree also that 'NO' 1970 L-78 Chevelle, or L-34 & LS-5 for that matter, received them, as they were a later issued, Non Cowl Ind., solid lifter engine only application air cleaner.



1970 L34 Air Cleaner =
𡒲 The Dual snorkel was not used on the L34 engine.
𡒲 A working Cowl Induction hood, you need the single snorkel with the rubber seal on top.
𡒲 A standard SS bulge hood, w/o the flapper door, you need the open element air cleaner.

Typically you find the open-element style with the foam seal that goes around the base and the single snorkel. This one is used on the Cowl Induction cars. It had a chrome lid in '71.

For non cowl-induction cars there was a closed element style with a chrome lid. It is most often seen with a single snorkel, but on cars that came without air conditioning they came with twin snorkels.

Each snorkel had the flapper valve (Thermac) to force air through the hot air duct that drew in air from the heat sheild near the exhaust manifold. This is not the same air cleaner as used on the '70 LS-6.

The same ones were used again in '72 but they dropped the chrome lid and the 'Turbo-Jet 454 365 horsepower' decal that they all used. The '71 big block engine decals were unique to that year BTW.

Notice the decal on the 1971 single snorkel version.

Notice each snorkel had the (Thermac) flapper valve.
