Emission years

I'm looking to get another truck and a SFA Chevy is one of the possibilities on my list. I'm hoping somebody could tell me what is the last year truck I could buy with out any of the emissions crap. No smog pumps, cats, miles of vaccume lines, ect. I use to have an 85 Blazer and junked all that stuff when I swaped in a new crate 350, but something like that wont pass inspection anymore. Thanks yall.

Re: Emission years

Rather than do that, id say look into what year it is that doesn' thave to pass smog anymore. Then you could do whatever you want.

Re: Emission years

Thanks for the advise, but we dont smog test here. Each vehicle has to have the emissions equipment that it came with from the factory to pass the safty inspection. I just dont want to buy a truck that all that's been yanked out of and them have to turn around and hunt it down in junk yards just to pass inspection. I'd rather buy a truck that never had it in the first place, just need to know when the "cut off date" was.

Re: Emission years

Re: Emission years

For the most part, 1979 and older 1/2 pickups with the 49 State Federal emission package would not have a catalytic converter. For the most part, 1980 and older 3/4 pickups with the 49 State Federal emission package would not have a catalytic converter. For the most part, most 1982 and older pickups with the 49 State Federal Emission package did not have a smog pump. For the most part, pickups starting in 1975 and newer will have a charcoal canister. For the most part, 1972 and newer pickups will have an EGR valve.

If I had to pick a truck that was going to be easy under the hood as far as the 49 State Federal emission package, I'd look for anything from 1974 and older.

In some cases, I've seen vehicle owners that will stuff small ball bearings in the vacuum lines next to emission equipment, which I guess looks OK for underhood inspections. [img]images/graemlins/blush.gif[/img] I guess a ball bearings inside a vacuum line is not as easy to spot on an inspection like a golf tee or small screw pushed into a disconnected vacuum line.

As far as a vacuum lines go, usually just a ported vacuum line to the distributor vacuum advance is needed, but maybe a main vacuum line to the power brakes would be a good idea also.

Re: Emission years

There's a good point. Stay away from trucks with the California emissions package.

Re: Emission years

I always thought 73 and older didnt have any emission [bleep] on them. Im PA we now have a visual [img]images/graemlins/mad.gif[/img]for the first time, its such a bunch if [img]images/graemlins/AR15firing.gif[/img]bull sh1t.
I found a garage that just does really half as$ inspections and dont bother checking under the hood. I guess it really depends if the garage is busy at the time or not
