Default 67 L78 Smog system

Hello all,

I’m looking for some help on a smog system for a 67 L78 car I’m working on.

Currently I’m installing the original engine and I’m having trouble trying to figure out the correct smog system layout. After searching online, I can’t seem to find any pics of one installed (at least on a 67) I can find 68/69 but not 67?

Thankfully the original owner saved all the parts he removed back in the early 70’s and I believe we have all the pieces.

After looking on the CRG site, assembly manual page 265, not a very clear diagram on how it’s mounted? I need to know how the adjustment bracket (belt tension bracket) is bolted up. I think it bolts to the water pump stud but something seems off, I installed it the same way the diagram shows but it don’t look right.

Anyone on here have any detailed pics of the pump mounted and also how the hoses are routed?

Any help would be much appreciated!

Thanks, Kurt

Dave, thanks for the help, but that don’t really show what I was hoping.

Much appreciated though!

Not an L78 but if you haven’t seen them already, there’s some great Smog equipped ‘67 L35 pics further on in this 01/15 thread, also don’t miss Bruce’s Camaros.net link in Post 5 which has some great ‘67 L78 info, click here…

Best of luck w/ your quest!

Pix from a '67 Chevelle L34. Note that the L34/L78 systems are quite different from the L35. Hopefully you have the pass side valve cover with the bracket.

Hopefully these are useful to you!
