turbo 6 bangers post here

Hey guys, here is my next question. While I was at the nationals last week I talked to a holley rep about his thoughts on my carb choice of a 350 2 barrel. He agreed that with a fairly stock motor and a turbo that is the correct choice, but he also told me I needed to have the carb modified. I knew I needed to change the float, but figured since I was running only 10lbs tops I wouldn't need to worry about having any other changes made. Thoughts?
