c30, how to pass California emissions

[A.Delaney]

Just curious. Is the truck checked to make sure it has all the original equipment on it? Or do they just test your exhaust to make sure it doesn’t put out more emissions than a factory 79’ would put out. I only ask because what if the truck had been swapped to an LS or something fuel injected? It could put out less emissions than a factory 79’ with a 454. Would it still pass?
