I'm waay over 650hp with a single Carter/Edelbrock style carb, currently a clone 9635SA 625cfm. Helps when a large percentage of the overall mixture ends up coming in under the throttle body :)
Wouldn't change it for the world at this point, easier to get races with it and I love the looks I get when I show someone what's under the air cleaner. Over the years I've tried just about every modification/calibration while tuning with a wide band, current calibration isn't far from out of the box.
