If its stock, unlikely anything special. I wouldn't take anything big and heavy unless you need it. Small stuff like a distributor may be good for parts or reuse. Old original small stuff may be handy to someone, and you can sell or give away. Plus won't take up too much space, IF you want to take it. Stuff like ballast resistors, connectors, and in particular any wacky pollution control stuff. Fan shroud, fan clutch, radiator and overflow is another grouping people are sometimes looking for. Again, depend on how much you want to have sitting at your place...
