Last year for rolling expemption in California was '75 so I do have to smog and that is why I was dissapointed. Actually, some good news is that I had to lean it out to get it to idle which means less CO emissions which are the only ones I am worried about. Soon as I hook up the brake pedal tommorow I'm going for a test drive... to the radiator shop because my current radiator can't even begin to keep up with the motor.
