Hey you guys. I might be coming into a 327 small block v8 Chevy and was wondering if it would be a hard swap to do. I live in CA and was wondering what i have to do to pass smog testing. I don't remember if there was anything smog related on my monte. If im able to im gonna convert the small block into fuel injection since i dont want the hassle of a carb and i need the efficiency for the mpg. What can i do the make this pass smog
