So there is no difference what is being bruteforced - tiny or huge archive.

Wrong. There is no "blocks" - winrar compress whole file at once, and known checksum (crc32) is for whole uncompressed file too.
Ofcourse you can try bruteforce smaller file in archive, or try found "stored" (uncompressed, only encrypted) files, but if such files absent in arc? =)
