1980 smog
hello well i finally got my truck, its a 1980 chevy truck. scottdale. c10 2wd light half ton.
will be posting in the projects section later this week. i have a question regarding smog in California. it seems the p/o swapped the engine out, from a inline 6 to a 350, however he did not put any smog back on the truck. my question is what do these truck have on them, smog pump, canister catalytic converter, things of that nature, i have original exhaust but there pretty well toast, if i could see some pictures of the engine bay and smog equipment i might know better what needs to be put back on. thanks and i hope i get some quick replys

Re: 1980 smog
That's strange how they left the EGR valve on (although disconnected) but removed everything else. Where those alan head pipe plugs are in the manifold is where the gas recirc tubes would be

Re: 1980 smog
thanks those pics helped me out alot, a few more questions now that Ive seen yours,
![]() what is this thing, (red circled area) ![]() the red one looks original but the black circled nuts look newish? should i only need three open? ok and the black circled area with arrow and ? mark, should i have a oxygen sensor on my exhaust? so far i haven't been able to find one on my exhaust system anywhere. i do however have a cat on the exhaust system. ![]() the red area have no holes? does this mean that the black areas are the only ones that need tubes?

Re: 1980 smog
This is the pics of the E xhaust G as R ecirculation tubes on my two 87's, the whole reason I mentioned the EGR valve in my first unread post. Both trucks bypass the #4 & #6 cylinders. Why??? I can't answer that question. Hope this helps.

Re: 1980 smog
And more still...Keep in mind this is an 87 R3500 GMC (first pics) and an 87 V30 (Chevy 4 wheel drive) in the second pics. Not sure where the dividing line is, they seem to be the same under the hood.

Re: 1980 smog
I don't have any 02 sensors on my truck as you can see in my pic. The valve on the right side of the engine you circled i believe is called the Early Fuel Evaporation valve (E.F.E). At least that is what i can find in my 1978 Chevrolet service manual. Looking at your circled pics. It seems that maybe someone has changed exhaust manifolds (but I'm not sure). I've never seen a manifold with two outlets before, just 4 outlets for the air ram system.

Re: 1980 smog
What you should do corey is contact your local smog referee. They can be a huge help when you need them. I found out from mines that my truck was a Cali built truck, and not a federal model. That made a big difference when restoring the truck back to smog legal.

Re: 1980 smog
The sticker on your core supports shows all of the smog requirements. This is what the smog shop will look at and compare your set up too.

i have looked at getting a new one from lmc just dont have the spare change at the moment to spring for one. maybe next month when bills and parts even out for my wallet. as for the referee, dont even get me started with those people. i called them and talk to a "expert smog person" the only thing he would tell me was that i needed the smog to beable to smog my truck, i asked him if he knew exactly what i needed, he wouldnt give me a straight awnser, so i asked if he knew anyone that could point me in the right direction and told me he couldnt give me personal information about smog information. i think i just got a bad apple but i sure wont be talking to them anytime soon. some time next week im gonna chat up a local smog shop that seems to be fairly popular, hopefully i talk to the right person and they will help me out.

Re: 1980 smog
I just got rid of my smog equipment, installed a set of headers and a new exhaust system. If you weren't so far away I'd say you could have the manifolds and air pump.
