Quote: What he's doing is making the intake side and the manifold side of the carb bigger (I don't know exactly how it's machined), but he has tested them on a flow bench and the stock flows at 199 cfm's and the new bored out carbs showed 234 cfm's. He also does some drilling to the slides, and polishes the slide. I don't know why. The test will be if it feels better, more responsive, dyno numbers...
Making them larger decreases the air velocity is that crucial for carbs? Or does he modify something to increase the velocity?
