If you want fuel moleage you will want hot exhaust going through the intake under the carb. This helps to vaporize the fuel. Edelbrock makes two 600 carbs one is calibrated for performance and the other one is calibrated for mileage. I would suggest you use an electric choke to help with start up. Take the time to set the choke spring and fast idle speed to YOUR likeing. You may have to adjust again when the weather gets colder.
