[1.6.4]Texture does not apply to Block

Hello,

I have got a custom Lilypad in my mod (Block and Item), they both work fine, but the texture only applies to the Item and not to the Block

Lifebelt = new Lifebelt(800, "Lifebelt"); //Block
        GameRegistry.registerBlock(Lifebelt, "Lifebelt");
        LanguageRegistry.addName(Lifebelt, "Lifebelt"); 
        
    LifebeltItem = new ItemLifebelt(8020, "Lifebelt"); //Item
        GameRegistry.registerItem(LifebeltItem, "LifebeltItem");
        LanguageRegistry.addName(LifebeltItem, "Lifebelt Item");

Anyone as an idea of why this doesn't work?

Also, the version is 1.6.4 and I can't chagne it
