I want to get a different pickup and I'm wondering what the differences are between Silverados' years 1994-1998. Those are the years I'm looking at and I'm looking for big differences like if one year the engines were bigger than the one before or if certain packages were only available for that year, etc. But if it's only minor things like changing the body shape slightly, or something of that nature, it doesn't matter as much. If one year sucks vs another, that's the type of answer I'm looking for.
