The out board carbs are stock, we did'nt do anything wild, just stepped up the center carb aprox. .003 in size. The guys at H&F Performance are super trick, they drilled the metering block and my motor loved it. These guys build Super Stock and Modified IHRA engines and they are GOOD. Other than that, Its all OEM, But remember, my motor is not that wild, just good parts.
