This carburetor uses a square bore bolt pattern, typical of mid 60's and newer Holley and Edelbrock 4bbl carbs. Most factory Corvette dual quad intake manifolds used the WCFB bolt pattern typical of mid 50's and early 60's carbs. These intakes will not accept newer 4bbl carburetors. To be sure, measure your bolt pattern. If it is 5 1/8" x 5 9/16" these carbs will bolt on. The old WCFB pattern is 3 3/4" x 3 7/8".
