having multiple instances of blocks with different settings in D7
There's no hook_block in Drupal 7. However if you take a look at your README file inside your D7 version of multiblock module, you can find how to do it:


  Example implementation of hook_block_info:

function hook_block_info() {
  $blocks['powered-by'] = array(
    'info' =&gt; t('Powered by Drupal'),
    'weight' =&gt; '10',
    'cache' =&gt; DRUPAL_NO_CACHE,
    'mb_enabled' =&gt; TRUE,
  );
  return $blocks;
}
