I cleaned it up some with some gas and manual labor.

1970 L-78 Elcaminos could not get the dual snorkle.Dual snorkles came out much later on in the 70 model year,long after the L-78 option was cancelled for Chevelle/Elco which were only produced for the first 90 or so days of production,before the LS-6 came out.

Hey Rick good to know info on the L78 only having an open element or Cowl Induction breathers.

What is your take on these two build sheets. Check out the code on the air breather. One is from an LS6 the other is from an L78.....





Thanks for your thoughts.

Both those cars did not have cowl induction.
Marked &quot;CP&quot; i think it was an open air element as closed dual snorkel element was marked &quot;CO&quot; (not 100% sure if i am correct)
&quot;DG&quot; was cowl induction.
There is also a &quot;SS&quot; code for 396 350 HP cars with open air element.

&quot;CP&quot; was an open element air cleaner.Same as &quot;SS&quot; code.

Sorry for jumping in on the O/P. Thanks for the info. Any idea why they would have two codes for open element cars. I have seen SS codes on other L78's and LS6 sheets as well as L34 cars. These are the only two I have with the CP.

I've seen it on a scarce few.No idea..it's an anomaly,as the vast majority used &quot;SS&quot;.

Was &quot;CO&quot; the only code for the dual snorkel air assembly?
