you are smog exempt. i have a 73 f250 with a 460, and when i asked about it i was told that anything older than 25 model years is exempt, but that law is about to change, and i think it is gonna be anything older than a certain year, no more of the whole "each year, another years worth of vehicles becomes exempt"
You guy's haven't been keeping up. The governator just signed into law, effective Jan 1, 2005, that the 25 year rule is no longer in effect. Anything from 1976 back is smog exempt. If your vehicle is 1977 and up you are stuck with smog from now on. Mine is a 1977 F250 and I am disgusted. One more year and I would have been exempt.
