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?
I'm not a machinist, all I can do is relay info from him. Maybe it's swirled like the head should be, or the intakes, or whatever he does, but the numbers are there and proven, both on the dyno and the flow bench. For the price, it looks like a very affordable upgrade for carbs, and you know they will fit just like stock! Like I said, I will post dyno numbers soon, I'm expecting delivery on these today, finally, after delays because of the custom intakes he was having machined from billet aluminum.
Always remember to be yourself. Unless you suck. Then pretend to be someone else.
