Why don't you specify the exact size of data that you want copied? E.g,
do something like this:

    dd if=big of=small bs=8M count=1K

This will copy 8,589,934,592 bytes of data from big to small. If you
want it to be exactly 8,000,000,000 bytes, you should instead use:

    dd if=big of=small bs=8MB count=1kB
