512 blocksize is almost never recommended. :)
Use atleast 1K. The FAQ has the explanation of
the terms blocksize and clustersize.

I have an ocfs2 file system with 4K blocks and 128K clusters--using it

Problem: Large number of small files (300 bytes or less) appear to
take much more space on ocfs2 than on ext2/3.

Will altering the block/cluster size on the ocfs2 file system improve
the situation?

yes. Normally a file will occupy a cluster for its content.
Since your file are 300 bytes or less, you may choose 512 as block size and 4K as cluster size.


Suggestions?
