I think you'd be shorting yourself, like going all out everywhere else then stifling it a little with a stock converter. A better converter can improve the performance of a stock powertrain with little or no sacrifices. I forget what cam you have. But, based on weight, gearing, engine's expected power band, intended uses, etc., a company specializing in converters can spec one ideal for you. I'm very happy with my CircleD converter. It drives almost like stock during normal cruising but, when mashing it, it rips to nearly 3,000 before it hits hard. I've towed with it with no problems. Don't forget the input seal on the trans while you're there.
