i've never purchased one either but you can get them in diffent ways. i don't really think that would make a cam considered part of the short block though. the harmonic ballancer is considered part of the short block but you can order a short block without one.

I always considered Top and bottom end a term to be used in reference to rebuilding or in need of rebuilding. The rotating assembly would be considered bottom end, and the valve train would be considered top end.
Things like a cam on a push rod engine would just be a cam. Just like a carb or intake/ exhaust manifold.
When I hear fresh top end, I think new or rebuilt heads. or fresh bottom end I thing rebuilt rotating assemby and possible port or hone work.
To me it does not nessesarly mean the cam, or anything else was replaced.
Dang, Im thinking to hard about this.

so when people say "rebuilt engine" do they normally just mean the top end??
I remembered when I blew a head gasket on my Lt1, it was still under warranty and the dealership said they would "rebuild" it.
I'm assuming all they did was head work/valvetrain/gaskets??? No reason to touch the crankshaft/rotating assembly.

I think its somewhat open for interpetation. My head hurts again.
