Attached is a Excel file (with a macro built in) which will create a Assembly Clone log file. This log file can be used with the clone dialog in NX, to specify the names for parts when cloning.
There's a Powerpoint that goes with it.

I didn't create it, but found it a few years back.
To me, using this would be the simplest way to get what you're after as you've got over 300 parts to name.

If it's a simply "replace all 320 with 170" you can probably do this by the name rule, but then the dialogs for exceptions are plain hell when your assembly has passed say 25 components in size.
so what you can do is load up the assembly into the clone function, set the name rule "replace 320 by 170" and other settings you prefer. Then do a dry run and save that information window as a plain textfile.
this textfile can be used as Anthony mentions above, but
you can before using it as the input for the clone do the manual edits you like to it, i.e set the fasteners to "retain" instead of "clone" etc.
try this on some really small assembly to see how to do this before you do the 300+.
