L78/LS6 EEC Emissions System

**MosportGreen66** · #1 12-04-2023, 04:12 PM

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

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.

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.
