I've done imports, wheeling, lowriding and more recently drag racing while building and enjoying my 63-64 chevy's at the same time for the last 26 years. No matter the version car guys and just older car kids. These old parts are all obsolete for looks more than anything. No way to know what car they came on or belong to. No way to tell what racing history if any they had. There are better heads and intakes for performance and much of the old cast iron stuff can be made to create some impressive power due to modern building. They look cool and that is about it. Unless you have a car to go with it and some history. They are museum pieces to me.
