The law says all vehicles 1968 and newer have to be tested. They are only required to pass at the standard they were originally built at . 1979 vehicle uses 1979 standard. We can avoid the test by putting antique plates on our cars(25 years or older) , but that restricts you to parades, club meetings, etc.Not daily driver . If you build a street rod, you go out and buy a title from a destroyed car and put it to it. Not exacttly legal, but you do what you have too.My original question was can a motor that is built to be around 350hp or better have a chance of passing the test. It seems alot of people with late 60's to 70's muscle cars, that are built up, are just going ahead and getting the antique plates.
