We all know you can get way more out of a production block than what's recommended. The key is bracing it up correctly. I'm sure if you use a main support and lifter valley braces you will add some much needed strength to it but we all know that regardless of how much you brace it up its gonna have its limits. A Dart block is definately a wise investment hands down. As for 331 or 347...flip a coin. Either one can make serious power with the right combo. Just my $.02
