I just tried a NAD27 -> NAD83 grid shift like this and it seemed to
be doing something:

warmerda at amd64[73]% cs2cs +proj=utm +zone=11 +datum=NAD27 +to +proj=utm 
+zone=11 +datum=NAD83
300000 4000000
300004.77       4000200.77 0.00

Could you be more specific about what you did, and also verify you have
the correct grids findable?  Setting the PROJ_DEBUG environment variable
set to a non-empty value can help determine if grid shift files are
successfully found.
