How can I display a block as a node?
I would do this from my custom module. I would create a men path and a page callback which renders the block.

/**
 * Implements hook_menu().
 */
function mymodule_menu() {
    $items = array();
    $items['my/block/path'] = array(
        'title' =&gt; 'Block As A Page',
        'page callback' =&gt; 'mymodule_block_as_page',
        'access callback' =&gt; TRUE,
    );  
    return $items;
} 
/**
 * Page callback the path for my/block/path
 */ 
function mymodule_block_as_page(){  
    $block = module_invoke('module_name', 'block_view', 'module_delta');
    return $block['content'];
}


If you go to the path my/block/path, you will see your block as a page/node.
