The nice thing though is the later engines have less emissions or less complicated emissions. I have no trouble running the smog equipment required for the year of the engine. The only reason to not like the smog stuff is if you want to hot rod it or you have a truck like my 85 with california emissions and can only use parts for a 85-86 truck for smog and there is almost nothing available.
