The carb pad height for the Offenhauser 5766 intake manifold is 4-5/8 inches in the front and 6-1/8 inches in the back, measured with a straight edge placed across the carb mounting surface. This gives it a pronounced angle from front to back. If you average these, the carb pad height is approximately 5-3/8 inches. Please keep in mind, this measurement is for the intake only and does not include carburetor or gasket thickness.
