I didn't think anything was exempt in California. Especially since California has had emission control specifications beginning with 1966 models. If they choose to exempt vehicles that old, like New Jersey has, then no. The exemption would be based on the model year of the vehicle, not the equipment installed on it. Hope that helps! Jim


California's smog standards are like most of the US. Pre 1976 model year vehicles are exempt, and that applies to the car; not necessarily to the engine. You may install whatever drive train you want in your pre-1976 vehicle and you're smog exempt. I have a friend who has an early 60" Impala SS and has a modern corvette engine in it. He doesn't have to mess with smog..... You can go the DMV website and they'll explain it in legalese.

Thanks for your input on this. I'm surprised that California exempts anything. They've been the strictest State for emissions inspection for many years! Several years ago New Jersey decided to exempt 1995 and older passenger vehicles, vans, pickups, etc. from emissions inspection simply because the State didn't want to spend the money to maintain the older tailpipe emissions testing equipment AND the newer OBD II plug in emissions testing equipment. Personally I think older models should be subject to a safety inspection even if emissions inspection are exempt. But that's just me. Thanks again for chiming in, good to know!! Jim


We Californians have to stick together; even if it does get us sweaty.
