To further clarify cobrakc's post, the original 2x4 intakes were designed for installation on Ford passenger car motors, that had the rear of the motor lower than the front by about 10 degrees. Not sure about the original Cobras, but the motors in the replicas are almost level, making the carbs lean toward the front and the rear carb higher than the front. It also can require a little creativity in setting the float levels on the carbs, since the carb float bowls are not level as originally intended.
