Have you had a look at the docu?
Look at
  http://www.gnuradio.org/trac/
and especially at
  http://www.gnu.org/software/gnuradio/doc/howto-write-a-block.html

Blocks in GNU Radio generally do not have a instrinsic speed but are 
constrained by the rate of their sources and sinks and of course by the 
speed of your machine. In a software-only (no USRP or Audio) 
applications you'd likely use gr.throttle.

Please be more specific in what you want to implement. Do you want to 
have very special sequences, or repeat sequences, or PRN? What do you 
need it for?
GNU Radio has a vector source, and you can load it with arbitrary 
values. You could also use a file as source and generate you data 
outside GNU Radio. Of course the file can be a pipe and you could use 
another program to generate your sequence on the fly.
