Located Blue Springs Mo. I have a 1967 coronet, with a built 383, four speed, TTi headers, exhaust, magniflows, tubbed. Thinking of adding dual quads, looking for the best type for most performance.


aboard. As you probably know, testing has shown that a dual quad system does not have a significant performance increase for the "street" over a properly designed single four barrel system. They do look awesome though and frequently need more maintenance. Lets see under the hood what you have now.
