Yes, it can be done.  You did not say which version of Emacs you are 
running, that might make a difference.  That said here is how I would 
do it if I were running version 21.3.

Load the ibuffer.el package, load the dired-x.el package.
The ibuffer.el package is available from: 
www.shootybangbang.com/software/ibuffer.el
The dired-x.el package is a part of Emacs but must be explicitly 
loaded/enabled in your .emacs.

Once you have these to packages active you can use the % g dired 
command to locate the files that contain block of text you want to 
replace.  Then you can use the C-u F dired command to load the files.
Once the files are loaded invoke ibuffer and use the / c command to 
limit the view to files containing the block of text.  Then use the t 
command to mark all the files.  Finally use the U command to replace 
the block of text defined by a regular expression with the new text.

There may be other ways to do this, but this is the easiest way that 
I know of using simple emacs commands.

Good Luck,
