How can I get some block of text by lines?

I have a log file with 6000000 lines and I want get just a block of 607366 to 700000.

You can use sed:

sed -n 607366,700000p server.log > outputFile.txt

If you want to use head and tail, this is the right way:

head -n 700000 server.log | tail -n $(echo 700000-607366+1 | bc) > outputFile.txt

or, shorter:

head -n 700000 server.log | tail -n 92635 > outputFile.txt
