I debated that same question. You'll spend a lot of money to lose a little bit of weight. If you're racing for money and need every last edge, it's worth it. Otherwise it's strictly for bragging rights. I race for points only, and didn't feel it was worth it the extra money.

After I blew up the stock block 427, I bought the Dart iron Eagle Sportsman strictly for track durabiility. For street use, I'd use a stock block.
