Intake, carb, air cleaner all have to go. You're a long way from a smog legal engine in Calif.
Were'nt you aware of calif emissions when you bought this?

Dude, you are screwed. It used to be easy to find a crooked smog joint that would hook you up with a smog check, but it gets harder every year.

i know bro i dont know what to do wether park it in my backyard and leave it there or sell it but selling it i would still need to smog it

[Ziegelsteinfaust]

If you were to sell it register it non-op.

Pull the engine, and sell it.

Then sell it as a project truck.

That might be enough to get out of trouble.

Or go to pick a part, and but a whole 77 motor. The put in on your truck.

Most of the compressors I have seen or on the passenger side so they are closer to the evaporator but it is possible to have one on the drivers side.
In the picture he has shown it doesn't look as bad as some here seem to be suggesting but again that is just my way of looking at it.
I would find out what is required first.
Once you know what you need you can go from there.
The open air cleaner is a no no but without better pictures I would not count out the manifold or carb.This is a 77 not a 2007 so the requirements are way easier to meet.Lots of 77's running around with headers a new manifold and carb passing smog every two years.
If it requires a stove pipe on the exhaust and you have headers you can take a 1.5 inch pipe 2 inches long and drill two holes through it and wire it to one of your header tubes.You then run some flex tube to the air cleaner.Total cost $5 and it passes.
On the intake does a 77 require a egr and hot air riser to pass? Does his manifold have both or niether?
I quick trip to pick-n-pull with a digital camera will let him see what comes standdard and what he needs.
I certainly wouldn't put a pick-n-pull motor in it thinking it will somehow pass.
We need more info.
Also were are you located? If your close by I can probably help you out.

Ive got a 77 Heavy Half that passes every year easily no matter where I take it. The only thing I can remember about the difference between the heavy half ton and the regular pickup is no need for catalytic converter and they dont really care what kind of exhaust you have as long as your smog pump is plumbed into your headers. Only reason I havent purchased headers yet.
Hopefully there are some pics below from my photobucket. Yes the AC compressor is supposed to be on the driver side. I inherited this pickup from my grandfather and it was never modified.
Here you should be able to see the plumbing into the header to the smog pump

Below is the overall engine with AC compressor.

below is my daily driver to work 15 miles each way. Just because....


If you have anymore questions or need help, let me know. Id think your "stove pipe" that you can also see in the first pic, will be the most difficult to find. I tried smogging it the first time without the stock air filter and using a 14" open element and was instantly told NO WAY. So I had to put this back on.

[LynnJr]

For the stove pipe read my earlier post about using a short piece of pipe wired to the header or manifold using some flex line.Its simple and its legal.

Thanks for the picture of the A/C compressor.My truck doesn't have it.

Negative. S.B. 1224 is D.O.A.

If you want to keep the truck, here's a few options to look into:

1. Spend a few hours at the pick n pull. Source missing emissions equip there.

2. Swap over to 91+* TBI. Visit the Ref and have him sign off on it.

In either case, an intimate knowledge of emissions equip is required. Obviously, option 2 is significantly more involved than option one, but I feel the payoff is greater.

The emissions laws are a hassle, no doubt, but they're not *that* bad once you know what you're doing.



*minimal emissions equipment compared to earlier years. Ex: no "smog" pump/a.i.r. tubes

[LynnJr]

Why would you have him switch to a 91 TBI?

Oh no, my truck passed with flying colors, I just thought that it would be nice if that was the case so I could take out the smog stuff and add things that I know wouldn't pass smog.

I bought a 76 with no engine for almost nothing because of the smog issue. I just bought a complete LS take out to drop in and the best part, is that there is no egr or air injection on this particular engine. The only thing to hook up is the EVAP in relation to smog. I am going to the referee and get the truck smogged as a 2002.

[1977cheyenne_C10]

can i use any complete engine like other year than 1977 or does it has to be a 1977 year model?

[Ziegelsteinfaust]

I believe you can use 75-78 or 79 as it will have the stuff you need.

If you want fuel injection TBI is a good idea mentioned above.

[LynnJr]

Why TBI? I am not getting why anyone would want to add TBI to a earlier truck what is the advantage?

[JCampbell]

I'm in the middle of a TBI swap right now on my '84.

I'm moving to WA in Oct and I'll be exempt up there, so I dumped the air pump and EGR valve, but as long as you have those items, the Ref should pass you.

Better gas mileage
Lower emissions

Two big reasons.

I have a catalytic you can have. I'm never going to need it. It came with the frame that is under my truck now. FREE... just come pick it up.

[zaccaglin]

The 81 I just bought didn't pass its first go. The idel emissions were in the 2000s hen they should of been under 250(so I was told by smog guy) rebuilding the carb now for go #2. As soon as the truck smogs and pink is in my hand it'll be forsale. I hate smog going vehicles and I hate ca..

Is this TBI you guys are talking about some kind of stand alone aftermarket set-up? or a factory set-up requiring all the electronics as well?

[406 Q-ship]

I am a past resident of The Peoples Socialist Republic of Kalifornia up to November of last year. There is a lot of bad information being past around in this thread. I did engine swaps in Cali and can tell you there is a lot of incorrect info even from Californians. DO NOT take the truck to a smog only station for they may report you to the DMV opening a whole new kettle of worms that you don't want (read BIG HUGE FINES). Find a person who has access to one of the books that the emission test stations used to know exactly what your truck has to have but only from someone you know that will not report your problem to the DMV. Is there am emission certification sticker under the hood (usually on the upper core support), it will tell you most of the information you will need. That sticker will tell you if your truck was a California certified or Federal certified (pray for Federal). At minimum you will need EGR, A.I.R. (air injection), a certified carb (back to a Q-jet or a Edelbrock), all the vacuum switches and controls, a OEM air cleaner (TAC), and a Catalytic converter (Cali cert only and that kills any long tube headers). This is off the top of my head and there may be even more stuff.

For the one who posted this picture, consider yourself REALLY lucky. You should fail the visual test.....no EGR.

[LynnJr]

And now there is even more bad information for him to read.

If he drives it to a test only shop as I suggested and asks them to do a visual so he can buy what it needs I have never had any trouble at all with the DMV as they wouldn't know and I live here currently and not from the past.I didn't tell him to put it on a tester and run it so his vehicle ID is recorded but I guess you missed that part? You make it sound like everyone is sitting around recording VIN's and they are not.

I also have long tube headers on my 1990 with a cat and they are not a problem at all in California.I don't know what county you were from but some are easier to pass in than others and they make 50 state legal long tube headers.

If he lived near by I would strip his current engine down add everything he needs and smog it the very same day then put it all back together again like he has it now and be done before dinner got cold.

[74 stepside]

This is the reason I spent a little more and got my 73, which wasnt the nicest truck Id seen for sale compared to others. These Ca smog headaches suck...

[1977cheyenne_C10]

would i need to have the same year block of my truck or can it be any engine?

You will need the same year or newer. Cant be older..
