Ok, I was thinking of having my hood punched with some louveres, but wanted some opinions of some of you who have your hoods punched. Would you do it again? Do you regret it? I know they look cool as hell, but after having them done, will I wish I hadn't? I know a guy who had them on a 55 Chev, and had the inside blocked off with a piece of stainless steel. The reason? It ran HOTTER with the louveres open than with the steel blocking them off. Help me decide before I get them done. Not that it matters, but this is on a 50 Chev. If you have pics, show them, so I can get an idea how I might punch them. Thanks!
