I love Darts too. In fact, I'm running 215cc Iron Eagles on the 383 in my '82 Z28 drag car. However, for a daily driven street engine, I prefer the Vortecs because of the tall high-flow smaller runner intake ports and the fast burn combustion chamber. The Vortecs bone stock with 170cc intake runners with 1.94/1.50 seriously outflow the Dart S/S's and World S/R heads and give 200cc Iron Eagles and World Sportsman II's all they want up to .500" lift. Their bigger heads kill the Vortec, but Dart nor World makes a comparable sized head that will perform as well or be as efficient as the Vortec. I know that sounds crazy, but it is true. That's why I'm so high on the Vortec. Check out this chart, because I know you racer types (Bob) are gonna want proof!
