L78/LS6 EEC Emissions System
 

Hi All,

We're looking for more information on the '70 LS6/L78 EEC system including the coal canisters, rubber lines, and others.

Does anyone have survivor photos they can post or share?

Thanks,
Dan

Is the Nova a Cali car Dan.?

Dan, in all likelihood you have seen these original photos before but for the benefit of others, these show some pretty good detail. Note also the NA9 decal on the top radiator cover plate in the middle. These were yellow.

Special charcoal can top for the Holley bowl vent line. Hard to find part.

Hi Jim, yes it is. Ordered to Allen Gwynn Chevrolet in Glendale (LA).


Thanks Rick. I did see those but it's great for others to see them too. It is a maze of tubes, fittings, clamps, special parts, canisters, etc. The goal now is to amass the parts. Longer term we'll consider installing it.

Thx Dan, didnt see the other post... that EVAP stuff is a bear, good luck with the hunt, will keep my eyes open

what does that center sticker look like?

Not the best photo but this will give you the idea.

Rick, you did a restoration on Mark M's 1970 Z28 and it had the NA-9 emissions package. Did it use the same radiator cover decal?

Unfortunately I never took a close up of the sticker. Most all of the decals came with the car from the owner before Mark. NA9 was listed on the buildsheet but if memory serves me correctly the 2 letter code for the decal was not shown on the BS.

One of the Yenko.net members bought the car, correct Rick?


Maybe he can post a picture?

That's some great stuff right there!

Yes, Harry Nye

Hello. I own the 1970 Z28 that rick restored for mark and here's a current shot of that decal. Going to post a few more pictures of Ricks restoration, engine shots 10 years after. Rick Nelson is all that and some.

Just a few more pictures 10 years after restoration with no Fluff.
Iam sorry Rick, these pictures shouldn't be in this thread but Iam so freeken stoked I own this car and your DNA is all over it.

Thanks for the pics Harry!:beers:



She still looks awesome!!!

Thanks. Cant wait for the nationals.

Awesome Z Harry! Can I trouble you to send detailed pics of the system? Details of hoses, lines, clamp color, canister, routing of such to carb, and gas tank?

Rick - did you restore to function (if it did anything originally??) or did you restore the system to look correct but it is functionless. Similar to rebuilding a smog/AIR system as non-operational?

Thanks,
Dan

Dan, go Non Functional, sacrilege to choke an SHP L78 like that! I know it will "look" perfect
