Model year and emissions equp. question
Howdy,
I am wanting to buy an old chevy or gmc pickup but don't want to worry about non-functioning or missing emissions components that will run me ragged trying to fix to satisfy the emissions inspectors. I would like to get as new as possible to get the benefit of power steering and disc brakes and the like, but still miss most or all of the smog crap. I have seen the page here as to what years had catalytic converters, but what are the other specifics by year; i.e - EGR, smog pump, etc. I had a '72 GMC that had no cats, but DID have a smog pump----go figure. Is there a page or thread outlining standard emissions equipment by model year, or could some kind soul shed some light on this? Thanks, Craig |

Craig,
I've never found anyone (including GM) who could give me a clear picture. Basically, it's very complicated to make generalizations. I found by accident, though, that the emissions test centers (at least here in IL) have a book that lists, for every year and model, which should have which components. Perhaps they'd let you look at it? The little bit that I know says that before 75, none had catalytic converters. Over 75, light duty emissions (1/2 ton, non 454) had cats. Not sure when other pieces changed. Good luck, Brian Brian |
