As I'm not an expert at all but as I want to know a bit more about differentiating big size Chevy's from end 50's to begin 70's, I open this topic on the forum...

Major question is: As I like them, I would like to know rougly what are the major differences between Bel Airs, Biscaynes, Impalas and other possible sister models (incl. wagons :wink:)?
Engine? Trim? Equipment?

Could somebody help? Is there a good doc somewhere? Thanks.
