Off-road and race vehicles can't be registerd in the first place so there is only a problem if you try to register them as a street car. They can be sold freely as race cars.

Here in Texas the testing areas are currently the Dallas/Ft Worth, Houston, El Paso areas. But come Sept of this year they are adding in the Austin area and that is me

Isn't this always the case. Although I haven't done this, my understanding is that you go to a "referee Inspection Station" (not sure if this is the correct name) to have them judge that your mod meets their requirements (not sure what that means). If it does, they will grant a certificate accepting the mod. You'll only have to do this once. Again, I've not done nor known anyone that has gone through this.

I think that your example of a crate motor is the most typical and logical of the mods that would be acceptable, tha rational being that a modern motor will product less emissions. I also understand that if you add a modern motor, you also are supposed to add all of the accompanying emission goodies such as O2 sensors and cats, if you don't have them now.
I hope this isn't necessary. I was going to simply do a swap and use all the current admissions equipment, air cleaner and hoses. I don't think smoggers look at the number on the block, or at least I haven't noticed it.
I spoke to The Engine Factory and they said they could build a motor with smog legal heads and manifold, use a quadrajet (mine is pre computer) and with the stuff switched over it should pass smog - no?

Will it pass? Depends where, I suppose. The first vette that I brought into CA got smogged at a place that I've used for years. The guy mucked around with it until it passed. He didn't have anything interesting to do and thought the car was cool. I don't think that the carb on that car was ever right and I'm positive that the cat was caked in carbon. The point being that the quality and knowledge of the initial inspection will vary considerably. It may pass once and not the second or third time or it may never be noticed. Sounds like your proposed changes should be pretty invisible.

This is really my pet peeve with the law. If the intention was to reduce emissions, then what you're proposing would obviously reduce the emissions, but according to the law this isn't rellevant.

I have a 75 here in Calif. look in the phone book under state office listings, there youll find the auto repair burea. Ive called them and they said that the laws are even confusing to them, but for the 75 year and prior the cars will not need to get smog checks every year or ever(even during title transfer). but if you end up getting pulled over by a smart cop, they could issue you a fixit ticket.beyoud that thats all I know.
soon to be 383ci vert. road ready calif member.
by the way they said that 76 and up will still be included in the system. . give the auto repair burea a call to double check. the dmv isnt a source to get info... there not the inspectors...

I couldn't agree more about the law- I don't think I'll have any problems. I am running my car now with a motor that burns some oil, original carb, heads, etc. with a new cat and all emissions and visual stuff in place it passes easily. I can't believe that a new motor with modern, 50 state legal heads will have a problem.

Great story about state run "smog only " stations.

When I first got the car, I had to take it to smog only station because I bought it from a guy who lived in Sacramento which was under special testing requirements. He didn't want to deal with it so I said sure I'll take care of it. The car was in really nice shape and I trusted the guy when he said it would pass.

So I find the nearest "smog only station" , about 45 minutes over the bridge in Richmond. The guy, who seems really knowledgable, tested the car. It passed but the timing was off a degree or two. No problem right- adjust it and I'm set. Except the smog only stations are just that - no adjustments or repairs. Pay for the smog test and go. What, huh?

So I drive the hour home, adjust the timing and take it to a local guy and pay him to put it on the dyno smog machine (which is not even required for such an old car) just to make sure it passes before I drive back over to Richmond from S.F. It passes no problem and I now pay him in addition to the paying the smog only guy. Back to Richmond the following week (you have to make an appointment and they are hard to get.) I pay the smog only guy one MORE time and guess what-- it passes, just the way it did the first time when the timing was a little off and the second time when I wanted to make sure it would. I paid for THREE smog tests, and spent 2+ mornings waiting around and driving back and forth.

Anyone want to move to California?

As far as pre 1975 american V8's, since there are no cats, what else could be missing as far as an inspection. Also, what levels would it take to pass a roadside sniffer test?

I've never seen a roadside inspection or sniffer. As long as you don't have nasty black stuff coming out of your pipes, you're fine. I've been running around all weekend w/o mufflers and haven't had one problem. Of course my '81 isn't loud enough to begin with.
