All of the most highly respected and world reknowned Chevy 6 engine builders like Frank McGurk and California Bill were ignorant if additional carburetion will not increase your fuel economy. The problem is that with additional fuel mix capability it will be difficult if not impossible to avoid using the extra horses. Drive exactly like you drive your under-carbureted machine today and you will see economy improvements. Cob it and you will be visiting the gas station attendant more often.
