I just purchased a 1984 Z28, PO replaced the 305 with a 350, stock head but he put the 305 intake, carb and exhaust manifolds on the 350. I have another manifold with a 650 Holly. If I put the intake and holly, what "smog" related stuff can I remove? Newbie

 

all of it the carb wont care and the motor will probably run much better if its tuned correctly
