I have a 1977 Blazer with the 350 V8. I did an engine swap about a year ago and didnt include any smog equipment when this happened. It was supposed to be exempt until the gov changed the law again. I am trying to figure out what equipment and hoses etc that I need in order for this to pass smog. Also I have heard that Nevada does not have any smog requirements, anybody know what their vehicle registration reqs are?
