I've read 73 and 78 are the last years for emissions exemption. Which is correct? Does it vary from state to state?

Tiger, I believe state to state, Here in washington state its 25 years. That means your not required to have a emission test to get plates, but if the vehicle has smog controls you are required to have them on the car and maintain them. My 81 is no longer a smog car and I've never heard of state patrol checking or ticketing anyone for the violation.
Thanks for the info. What if you're replacing an original engine with one that doesn't have the emissions stuff, eg. dropping in a crate engine without smog controls?
