Well Pedro, the standards for a '74 are a lot easier than those of a 1980.

The funniest thing in all this is the visual inspection. Everyone saw the numbers above -- VERY clean running car.
Those numbers came from a car that has fake connections to the canister, and EGR valve that does nothing and an A.I.R. pump that does not blow air. If it were not for the visual inspection I could install regular headers and STILL pass. But since they want to take a peak, I am currently stuck with the stock exhaust. I can not even switch to dual convertors as that is against the law, federal law.

As for taking it to a "friend" that does emissions testing, like they do in other parts of the country, we can't here. The emissions testing is done by state employees at a state facility that is monitored at all times. Big signs saying "tipping" is a crime there. So, I can't find a guy who will just sign off on the slip. It has to be done by the state government and their computer controlled sniffers and dyno.

Another funny thing is when they place it on the dyno to test it, an employee must be in the drivers seat doing the throttle and brakes. The owner must stand in a booth away from the car. But, we can see the computer speedometer on the dyno, and it has a range that they must stay in. On my year it is a constant 32 - 37 mph.
Well, this guy climbs in, starts it up, drops it into gear and hits the throttle............

He was just a little surprised as the damn thing just about climbed out of the rollers and was past 60 MPH before he knew it. He just looked over his shoulder at me and flashed me the biggest smile. :D

So, tomorrows project is to remove the EGR, AIR pump, vacuum lines and AIR pipes and hoses until next November when I have to put the ornaments back on the engine.

I will do some before and after pics. of the motor and post them here tomorrow.

 

Nice job, Brian!! I was thinking that I would keep my '74 registered here in Ca once I get out to AZ..... It will be exempt in 2003...... They will probably change the law so who knows if I should do that or not!!

Congrats! :cheers: :cheers:

I hope so.... Also, from what I've read, the test in Tucson is not this dyno type. Must be more forgiving....

This sux big time! To me this means I'd have to put back the original intake, or get an EGR Performer #3701. :cuss Well, it could be worse: at least I don't have to mess with cats or AIR.

:lol: :lol: :lol:

Depends on the year. My 68 Camaro and 67 Firebird (when I had it) only had to do the dyno test if they failed the standing tailpipe test. I think anything 74 and up has to do the dyno test regardless. I lived in Tucson for 21 years (Born and raised).

Everything 67 and up has to go through emission. :bs

Thanks for clarifying it, Steve!

BIG :bs

It surprises me that MA--the state where you can't buy beer on Sundays--is actually one of the most lax in terms of emission regulations.... :crazy:

-Pedro

 

Maybe, maybe not. Like it was said, Tucson is more forgiving as far as standards.

I sent an e-mail to the state of AZ to find out what my requirements were. You can also send an e-mail to them. The contact I have is a John Gibbons, e-mail is Gibbons.John@ev.state.az.us

Here is what he said about mine.

Bryan,

In the Phoenix area a 1980 Chevrolet, Corvette is inspected for the following emissions control devices: Air Injection system; evaporative emissions system; positive crankcase ventilation system; catalytic converter: functional gas cap. In the Tucson area we only inspect for the air injection system, catalytic converter and functional gas cap.

I hope this information helps.

John Gibbons, Manager
Inspection and Compliance Unit
Air Quality Vehicle Emissions
Arizona Department of Environmental Quality

Hope this helps all of you planning to move to the now "less smoggy" Arizona that I have provided for you all ...........

 

Hey, that's interesting: he didn't mention EGR! I guess things wouldn't be so bad... Cool!

I just emailed another person, responsible for the testing in the Tucson area. I'm particularly interested in knowing what is tested and what are the standards.

-Pedro

 

My 68 ZZ3 put out 70 ppm HC at idle (400ppm is the max) with only A.I.R. as a pollution control component. Your car, being much newer and having more pollution control stuff on it, is very, very clean. It'd be interesting to see rear wheel horsepower numbers. My 68 was right at 290RWHP.

 

I just got a corvette a littel wihel ago and its grate it got an edelnbrock engine in there almost no miles on, it love the car. Almost done fixing the electrical crap but this thing didnt pass the smog check(not even close i dont remember the #rz only that i was cursing a lot when i saw it).what my cuz did he has a 1996 camaro he put in a 500ci 8.4L engine into it and as you might think he would never pass smog so he payed extra for the smog check. i live in Cali so its prity harsh. so i when to the same shop as he did, smog guy only took 100 bux :blueangel: hey if you want to put some crazy azz crap in your car and still drive it legaly its a good way to go. :seeya

With the right tune you should be able to pass most of the early emission standards. But it will have to be an "emissions" tune, not a "performance" tune. Then just retune it after passing.

One thing to not in the fine print on the GM performance crate engines, they are for use ONLY in pre 75 cars.

tom...

 

WOW ! Thanks for the credit :cheers:

And I thought that all I was going to get credit for was putting that dang little "RUBBERMAID" sticker on your license plate :cool:

 

Az here also but down in Pima County {Tucson} need to pass the damn emissions. Would like to get rid of the Cat and OPEN up the Exhaust.
Later
Ken

 

I got one more emmission test left this year , it'll be 25 years in 2003 the cats are coming off , have duals now .. then i'll go for the high end options .. :yesnod:

 

Sorry, no credit for that. It fell off somewhere...... :(

 

Yeah Minnesota!

454, side pipes.

 

Where there is a will there is a way, and you found it. :D :D

 

:cool: Congrats! Chris (74 Vette) Is going to love to see this! He has been strugling with the same!!!! CONGRATS GREAT WORK!!!!

 

In case anyone is interested, here's the response I got from the guy in Tucson:

No "visual inspection".... Not bad, really.... But Arizona should adopt more sensible emissions regulations. I mean, testing a '67 vehicle for emissions is ludicrous. Those vehicles are few and in most of the cases well-mantained and treated as classics. They should focus on the real problem, the 80's and 90's use-until-it-dies POS's.... JMHO.

-Pedro

 

Pedro,
This does not apply to your '74 but I inquired of the EPA about emission "standards" for older cars and I got this back from them:
Hummm, no Federal "standards" for pre 1972 model year. Wonder what the state is measuring. :confused: :confused:

tom...

 

I wonder if the owner of a 67-72 vehicle could legally fight the state and win.... :confused:
