'85 smog equipment

[PhoenixFear]

This truck I bought in MI has no smog equipment at all. The 350 has been built by a speed shop down in Tennessee I believe, and all the ports and stuff have been plugged. My question is this. What would be a good comprehensive list of smog junk to put back on the vehicle to pass smog?
Also, would it be worth it, and what kinda guarantee would I have that it would even be able to pass? I personally was thinking cats, O2 sensors, egr, pcv, canister, and air pump. This is in Cali. It is either that or I might have to figure out another way to do this. I was just considering selling this truck however it would definitely put a huge damper on the price since it can't even be smogged. Thanks.

     I feel your pain.  You are on a good start with getting all the smog parts.  I have done this on a 79 and spent a lot of time at pick-n-pull.  As long as they haven't modified the engine with racing parts then you should be able to piece it back together.  There are some racing parts that are listed as illegal period in california.  Don't know what part of Cali you are in but i am in Sac, if close I can help if wanted......Tom

There are a few counties that dont need smog. So check to see if your county qualifies before buying stuff.

Yeah my county does, it sucks. I might just have to find another way. Basically it has a 350 with who knows what internals and heads, a Holley carb that is all plugged off, some long tube headers and a quiet exhaust with no cats or anything, just pipes and mufflers.
Perhaps I can just throw everything on that I think I'll need and take it to a test only place and see what they say.

    That's what I would do first.  But check for the crossover pipe, everywhere I have taken my other trucks they always checked to see if it was on there ( unless you got a rare factory dual exhaust, just not sure that had those for that year).  That is why I have pre 75 trucks now.  Anyway, I have done it in the past and it isn't that hard, just takes some time and effort.....tom

    Does it have the underhood smog/ vacuum lable??? That would be the place to start. Still have the OEM intake?? That makes it a lot easier, as you have all the ports needed. I'm in the process of replacing smog stuff on an '82 305 cause I think smog testing is comming back, (halted a couple years ago) and it would be a lot easier with the OEM intake. For example, non smog aftermarket intake has no spot for a Thermal Vacuum Switch (TVS)or EGR, and, non smog carb does not have enough ports. So for me the big items would be a smog carb and intake, not to mention the Air Injection with plumbing to the exaust manifolds if it had it. And I agree, "cats, O2 sensors, egr, pcv, canister, and air pump".
  I found a canister at the local pick & pull, got it on but it's not right (full time vacuum) because I need a port in the intake for a TVS, and later EGR. So needless to say, been keepin an eye out for a OEM 305 or aftermarket smog intake.

 Another thing to consider is what smog items the tester must visually verify/ see?

   I do not know the critical/ minimum systems needed to get emission levels where they need to be.  Any Smog Experts out there??? I imagine Cal is pretty tough though, but not a problem if your willing to hook it back up. The Chilton's # 28622 has the smog labels for 1985's.

Like I said, I literally have no smog equipment at all on there. I have a Holley carb on there, so obviously that probably isn't legal. I do have the sticker under the hood, would be a good reference. I am almost thinking I might have a nightmare ahead of me though, it may just be easier to take the entire engine out and shove a stock one in. Who knows if my engine will even respond with all the smog stuff on it? It may just make it run a ton worse to the point where it won't pass. I remember when I did my Jeep, the smog certificate had a certain number of parameters that it needed to pass, at different speeds. Such as a 15 mph, 25 mph, and a 35 mph I think or something.

  That Holley could possibly be a smog carb, identify it. The biggest part IMOP is the intake. Did they replace the OEM exaust manifolds and what intake is on there? If the engine is in decent shape, I don't see why it would'nt conform when properly tuned with all the stuff. Now if the rings or valve seals were passing oil, that's a different story (compression test etc.). My truck like yours has had all smog removed, all that is needed is the complete intake w/ carb, dist & air pump w/ bracket and exaust manifolds. So i'm hopin to be the first at a 305 when it hits the local pull & pay. It's a PITA don't get me wrong, but can be done. I'll bet there are folks on this site that have exactly what I'm/ we're lookin for!!! But I guess it also depends on how much time you have, and who's doin the work...  I should have held out for a computer w/TBI, easier to hit the smog numbers and as a daily driver, extremely dependable, easy to trouble shoot and pretty much bullet proof.  Seein your location though, I feel your pain.

[PhoenixFear]

I forgot what carb it was exactly, it was an electric choke model and whatnot. I believe there is an Edlebrock manifold on there, long tube headers and true dual exhaust. I guess it is illegal in CA to sell a catalytic converter in a junkyard, otherwise I would just snag the entire exhaust system off right at the manifolds.

[fred75]

  Yup, we have the same Mods, welcome or not!!! And if I was a betting man, not a smog carb.

[PhoenixFear]

Yeah I'd agree, probably not a smog carb. I could try my luck at a junkyard and pull everything I could possibly think of but that might cost a few hundred bucks.

[fred75]

  Should'nt be that much. I got a complete intake w/ throttle body for abt $125.00. Was at the yard today and there was a complete intake off an '85 with a quadrajet. Those quadrajets are complex (lotta stuff), but once you get them right their pretty much bullet proof. If I had to go that route, I would find someone who really knows thier stuff on those an get one rebuilt, or one would pay in the neighborhood of $325 and up. I think $150.00 would have taken the whole deal. Just need the exaust manifols after that. The rest is small stuff. But that's at a U Pull it off yard. Before I do anything else, I need to see if this 350 throttle body would work on a 305. A lot less emission stuff with the TBI, but you have to work the computer into the mix. There's outfits that make the computer harness's. Those quadrajets are complex (lotta stuff), but once you get them right their pretty much bullet proof.

  Since the Calif Govmnt forces everyone in the state to continusly buy new cars, the used stuff should be plentyful I would think. Or have they put such a burden on it, it all goes to scrap???

Looks like they just check for cats and your gas cap

Used stuff for this truck is cheap, however it is the stuff I can't legally buy that is expensive. Since I can't buy a cat in the junkyard, I'll have to look to Summit Racing or a parts store to buy a 50-state legal cat. They run I think $150 each or so. Then hit up the junkyard for the smog carb, and the intake, and the manifolds, and the air pump, all the vacuum accessories, canister, and custom make an exhaust for it or find someone who has a stock exhaust for it, and then the O2 sensors... the list goes on. The more I think about it, the more I really don't want to deal with it. This truck probably isn't worth hardly anything either, especially since it isn't legal here. I really like this truck though and it is extremely dependable.

That's for TN.
