You'd need to recompile from source, and tell the configure script
which block size you want. (It looks like the MSVC build scripts
know how to set this, but I have no idea exactly how to set the
blocksize option with them.)
By and large, people haven't found that adjusting these values buys
a whole lot, which is why we've never bothered to make them adjustable
short of source-code changes.
